OBJECTIVE:
To explore the clinical characteristics and gene variant of a fetus with Farber lipogranulomatosis caused by ASAH1 gene variant.
METHODS:
A fetus with Farber lipogranulomatosis caused by ASAH1 gene variant diagnosed at Women and Children's Hospital of Ningbo University in August 2024 was selected as the subject. Clinical data and abortion tissue samples of the fetus and peripheral blood samples of its parents were collected for whole exome sequencing (WES). Sanger sequencing validation and bioinformatics analysis were performed on candidate variants. This study was approved by Women and Children's Hospital of Ningbo University (Ethics No. EC2020-048).
RESULTS:
Generalized skin oedema, pericardial effusion, right pleural effusion and increased bowel echogenicity of the fetus were founded by prenatal ultrasound. WES revealed that the fetus has harbored a homozygous c.101C>A (p.Ser34Ter) variation in exon 2 of the ASAH1 gene. Sanger sequencing confirmed that both parents carry the heterozygous nonsense variation c.101C>A (p.Ser34Ter) in ASAH1 gene, which has not been included in databases such as HGMD, ClinVar, 1000 Genomes, ExAC, dbSNP, and gnomAD. Based on the Standards and Guidelines for the Interpretation of Sequence Variants of the American College of Medical Genetics and Genomics (ACMG), the variant was predicted to be pathogenic (PM2_Supporting+PVS1+PM3_Supporting). The AlphaFold3 model protein structure prediction reveals that the c.101C>A variant caused the premature appearance of a termination codon, resulting in only a small partial α-helix structure in the N-terminal of the encoded ASAH1 protein, with the complete loss of the α-helix structure in the core domain, which might lead to the loss of function of this protein.
CONCLUSION
The c.101C>A (p.Ser34Ter) variant of the ASAH1 gene probably underlay the Farber lipogranulomatosis with hydrops fetalis in this fetus. The newly discovered c.101C>A (p.Ser34Ter) variant has enriched the mutational spectrum of Farber lipogranulomatosis.

Chinese Journal of Medical Genetics 2025;42(4):460-468
OBJECTIVE:
To explore the genetic characteristics of a fetus affected with Structural heart defects and renal anomalies syndrome (SHDRA).
METHODS:
A pedigree with SHDRA (fetus and the parents) who had visited the Affiliated Women and Children's Hospital of Ningbo University in April 2023 was selected as the study subject. Clinical data of the family were collected. A total of 10 mL of amniotic fluid cells from the fetus and 5 mL of peripheral blood samples from the parents were collected for genomic DNA extraction. Trio whole-exome sequencing (Trio-WES) was performed, and Sanger sequencing was used to validate candidate variants in the family. The identified variants were classified according to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as the "ACMG Guidelines). Relevant research literature on SHDRA in domestic and international databases were searched for literature review. This study was approved by the Affiliated Women and Children's Hospital of Ningbo University (Ethics No. EC2023-094).
RESULTS:
In this family, prenatal ultrasound at 18 weeks of gestation revealed left renal multicystic dysplasia in the fetus. After birth, the infant exhibited an ostium secundum atrial septal defect, patent ductus arteriosus, and left renal multicystic dysplasia. Trio-WES revealed that the fetus had carried c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) compound heterozygous variants in the TMEM260 gene, which were respectively inherited from its father and mother. According to the ACMG guidelines, the c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) variants were classified as pathogenic (PM2_Supporting+PVS1+PP4) and likely pathogenic (PM2_Supporting+PM4+PM3+PP4), respectively. According to the literature search strategy set for this study, a total of 6 literature was retrieved, involving 25 SHDRA patients from 20 families. Together with the patients in this study, there were 14 TMEM260 gene variants, most of which were frameshift variants (7 types) and had located in exons 3, 11 and 13. The main clinical features of SHDRA were congenital heart malformation, renal abnormality and neurodevelopmental abnormality, and there was a lack of genotype-phenotype correlation.
CONCLUSION
The c.344dup (p.L116Afs*32) and c.90_104dup (p.Ala31_Ala35dup) variants of the TMEM260 gene probably underlay the SHDRA in this family. Above finding has provided a basis for clinical diagnosis and genetic counseling for the family.

OBJECTIVE:
To explore the clinical characteristics and variant of FBP1 gene in a child with Fructose-1,6-bisphosphatase deficiency (FBP1D), and review the literature on the clinical characteristics and gene mutations of FBP1D in the Chinese population.
METHODS:
A FBP1D proband due to variant of FBP1 gene who was admitted to Women and Children's Hospital of Ningbo University on August 10, 2021 due to "vomiting for 1 day" was selected as the study subject. Clinical data of the child were retrospectively collected. Whole exome sequencing (WES) was performed on the child, and candidate variants identified in the child were validated by Sanger sequencing in both the child and his parents. The difference between wild type and variant FBP1 protein were compared using AlphaFold v3.0.1 and PyMOL v2.5.6. The pathogenicity of candidate variant was rated according to the Standards and Guidelines for the Interpretation of Sequence Variants released by American College of Medical Genetics and Genomics (ACMG) (hereinafter referred to as ACMG guidelines). Using keywords such as "FBP1 gene" and "fructose-1,6-bisphosphatase deficiency" both in Chinese and English, relevant literature on FBP1D patients caused by FBP1 gene variants in the Chinese population were retrieved from the PubMed database, CNKI, and Wanfang Data Knowledge Service Platform, and the genetic variant and clinical phenotypes of FBP1D patients reported in the literature were analyzed. The literature retrieval time was set from the establishment of each database to October 31st, 2024. This study was approved by the Women and Children's Hospital of Ningbo University (Ethics No.: 2020-048).
RESULTS:
The proband was presented with repeated infections, nausea, vomiting, and mental illness. The auxiliary examination revealed hypoglycemia, acidosis, liver and kidney dysfunction, hyperlipidemia and hepatomegaly. WES and Sanger sequencing revealed that the child has harbored compound heterozygous variants of the FBP1 gene, including a de novo nonsense variant c.778G>T (p.G260*) in exon 6 and a maternally derived missense variant c.923C>G (p.P308R) in exon 7. The c.923C>G was known as a likely pathogenic variant, while c.778G>T has not been included in the databases such as HGMD, ClinVar, 1000 Genomes, ExAC, dbSNP, and gnomAD. Protein structure prediction shows that the c.778G>T (p.G260*) variant may result in a premature termination codon, resulting in loss of a β-fold in a core region, which may significantly reduce the stability of its protein product and affect its function. Based on the ACMG guidelines, the c.778G>T (p.G260*) variant was rated as likely pathogenic (PVS1_Strong+PM2_Supporting+PP4+PM6). Literature review has identified 32 patients from 23 Chinese families with FBP1D due to FBP1 gene variants. Together with the case reported in this study, in total 33 patients were analyzed. Among them, 22 cases were males (66.7%) with hypoglycemia, metabolic acidosis, vomiting, seizures, hyperlactatemia, and ketosis as the primary clinical phenotypes. After treatment, only 1 case (3.0%) died due to cerebral hernia, while the remaining 32 (97.0%) had favorable outcomes. Four cases (12.1%) exhibited developmental delay. A total of 66 FBP1 gene variant sites were identified, which involved 22 variant types, predominantly missense mutations (31 gene variant sites). These variants were mainly located in exon 7 of the gene (25 variant sites), with c.490G>A (16.7%, 11/66), c.960_961insG (19.7%, 13/66), c.355G>A (12.1%, 8/66), and c.704delC (9.1%, 6/66) being the most common variants.
CONCLUSION
The heterozygous variant of the FBP1 gene probably underlay the FBP1D in this child. Above finding has enriched the phenotypic and mutational spectrum of the FBP1 gene and provided a basis for genetic counseling and clinical decision-making.

OBJECTIVE:
To apply optical genome mapping (OGM) technique for the analysis of genetic etiology in two rare families with complex chromosomal rearrangements (CCRs) and to provide precise reproductive guidance to them.
METHODS:
Two Chinese families diagnosed with chromosomal rearrangements by chromosomal microarray analysis (CMA) or whole-exome sequencing (WES) between June and December 2023 at the Affiliated Women and Children's Hospital of Ningbo University were selected as the study subjects. In both cases, unbalanced chromosomal translocations were suspected. Clinical data were collected, and peripheral blood from the couple, amniotic fluid sample and aborted fetal tissue was subjected to combined G-banding karyotyping and OGM for comprehensive genetic analysis. This study has been approved by the Medical Ethics Committee of the Hospital (Ethics No.: EC2023-094).
RESULTS:
In family 1, the fetus was signaled to have abnormal chromosome 7 by non-invasive prenatal testing (NIPT), prompting amniocentesis and CMA detection. In family 2, a pregnancy loss had occurred at 10 weeks' gestation, and trio-WES was carried out. Both fetuses were found to harbor copy number variations (CNVs) suggestive of unbalanced CCRs. Further analysis with OGM has revealed that, in family 1, an unbalanced rearrangement involving chromosomes 7, 8, and 10 was carried by the fetus and the pregnant woman, which has formed der(8) and der(10) derivative chromosomes. In family 2, a maternal CCR was found, which involved chromosomes 2 and 13 with seven breakpoints, resulting in unbalanced fetal CNVs. After genetic counseling, family 1 opted to continue with the pregnancy, considering the woman's normal appearance and inheritance of the rearrangement. For both families remained to have a risk for unbalanced rearrangements in subsequent pregnancies, preimplantation genetic testing (PGT) was recommended.
CONCLUSION
In both families, the OGM has precisely delineated the genetic basis of fetal CNVs and mapped the maternal CCR breakpoints, providing critical insights for genetic counseling and reproductive decision-making.

Objective:To explore the genetic basis for a fetus with Cardiac valvular dysplasia type 1 (CVDP1).Methods:A CVDP1 fetus identified at the Ningbo Women and Children′s Hospital on July 7, 2022 was selected as the study subject. Clinical data of the fetus was collected. The fetus and its parents were subjected to trio-whole exome sequencing (trio-WES), and candidate variants were verified by Sanger sequencing.Results:The fetus had exhibited generalized edema, complex cardiac malformation, abdominal effusion, and enhanced intestinal and renal parenchymal echoes. Trio-WES revealed that it has harbored compound heterozygous variants of the PLD1 gene, namely c. 2977C>T (p.R993*) and c. 1460G>A (p.W487*), which were respectively inherited from its father and mother. Neither variant was reported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 2977C>T (p.R993*) variant was evaluated to be likely pathogenic (PVS1_Moderate+ PM2_Supporting+ PM3+ PP4), whilst the c. 1460G>A (p.W487*) variant was evaluated to be pathogenic (PVS1+ PM2_Supporting+ PP4). Conclusion:The c. 2977C>T (p.R993*) and c. 1460G>A (p.W487*) compound heterozygous variants of the PLD1 gene probably underlay the CVDP1 in the fetus. Above discovery has enriched the mutational spectrum of the PLD1 gene and provided a guidance for genetic counseling and prenatal diagnosis in this family.

Objective:To explore the genetic etiology of a child with Cowden syndrome 1 (CS1).Methods:A child who had visited the Ningbo Women and Children's Hospital on August 26, 2022 was selected as the study subject. Clinical information of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his family members and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing.Results:The child, a 13-year-old boy, had manifested with severe mental retardation, hyperactivity, autistic behavior, sparse and prominent teeth, macrocephaly, and skin freckles on the penis. His mother had presented with multiple papules, hamartomatous polyps, thyroid adenoma and macrocephaly. WES results revealed that the child has harbored a nonsense c. 781C>T (p.Q261*) variant of the PTEN gene, which was inherited from his mother. Based on the guidelines from the American College of Medical Genetics and Genomics, the c.781C>T variant was classified as likely pathogenic (PVS1+ PM2_Supporting). Conclusion:The c. 781C>T variant of the PTEN gene probably underlay the pathogenesis in the child and his mother. Above finding has facilitated genetic counseling for this family.

Objective:To explore the clinical characteristics and genetic etiology of four children with Phelan-McDermid syndrome (PMS).Methods:Four children who had visited the Affiliated Women and Children′s Hospital of Ningbo University between June 2, 2022 and May 8, 2023 were selected as the study subjects. Clinical data of the children were collected. Genomic DNA was extracted from peripheral blood samples of the children and their parents and subjected to whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing and quantitative PCR (q-PCR) analysis. This study was approved by the Medical Ethics Committee of the Affiliated Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048).Results:All children had presented with speech and language delays and intellectual disability. Children 3 and 4 also presented with autistic behaviors. WES showed that the children 1 and 2 had respectively carried a heterozygous c.731T>C (p.Leu244Pro) and a c.2782_2851del (p.Gly928ArgfsTer4) variant of the SHANK3 gene. Sanger sequencing confirmed that their parents did not carry the same variant, suggesting that they were de novo in origin. Children 3 and 4 had respectively harbored a 121 kb and 52.02 kb heterozygous deletion at chromosome 22q13.33, which had both encompassed the SHANK3 and ACR genes mapped to 22q13.33. q-PCR results showed that the deletion of SHANK3 and ACR genes were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 731T>C and c. 2782_2851del variants were predicted to be likely pathogenic (PS2+ PM2_Supporting+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PS2_Supporting), respectively. Furthermore, the 52.02 kb and 121 kb heterozygous deletions in 22q13.33 were both predicted to be pathogenic (2D+ 4C, 1.05 in score; 2D+ 4C, 1 in score). Conclusion:The four children were all diagnosed with PMS by genetic testing. Above finding has enriched the phenotypic and mutational spectrum of PMS, and provided a basis for clinical diagnosis and genetic counseling for their families.

Objective:To explore the molecular basis for a Chinese pedigree affected with Achromatopsia (ACHM).Methods:A pedigree with ACHM which was admitted to the Women and Children′s Hospital of Ningbo University on April 14, 2023 was selected as the study subject. Whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing and bioinformatic analysis. Related literature was reviewed, and clinical and genetic features of Chinese patients with ACHM due to variants of CNGA3 gene were summarized. This study was approved by the Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048). Results:WES revealed that the proband and his younger brother had both harbored compound heterozygous variants of the CNGA3 gene, namely c. 1190G>T (p.Gly397Val) and c. 2013del (p.Gly672ValfsTer69), which were respectively inherited from their mother and father. The c. 1190G>T was a known pathogenic variant, while the c.2013del was unreported previously. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 2013del variant was predicted to be likely pathogenic (PM2_Supporting+ PVS1_Moderate+ PM3+ PP4). Literature review has identified 41 CNGA3 gene variants among 43 patients from 38 pedigrees, most of which were missense variants and had located in exon 8. Most patients were males, with nystagmus, photophobia, amblyopia and other symptoms during infancy/childhood as the main clinical manifestations, and there was a lack of genotype-phenotype correlation. Conclusion:The c. 1190G>T (p.Gly397Val) and c. 2013del (p.Gly672ValfsTer69) variants of the CNGA3 gene probably underlay the ACHM in the proband. Discovery of the c. 2013del variant has enriched the mutational spectrum of the CNGA3 gene and provided a basis for genetic counseling and reproduction guidance for this pedigree.
