ObjectiveTo address the challenges of unstructured classical Chinese expressions, nested entity relationships, and limited annotated data in famous traditional Chinese medicine(TCM) case records, this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping, aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction(CasRel) model for TCM semantics was designed, integrating a pre-trained bidirectional encoder representations from transformers(BERT) layer for classical TCM texts to enhance semantic representation, and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model, combining data augmentation and entity mapping, outperformed the pipeline-based Bert-Radical-Lexicon(BRL)-bidirectional long short-term memory(BiLSTM)-Attention model. The overall precision, recall, and F1-score across 12 relation types reached 65.73%, 64.03%, and 64.87%, which represent improvements of 14.26%, 7.98%, and 11.21% compared to the BRL-BiLSTM-Attention model, respectively. Notably, the F1-score for tongue syndrome relations increased by 22.68%(69.32%), and the prescription-syndrome relations performed the best with the F1-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts, offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation, prescription optimization, and drug compatibility, providing a methodological reference for TCM artificial intelligence research.

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 genetic etiology of a child with Brain small vessel disease 1 with ocular anomalies.
METHODS:
A child who was admitted to Ningbo Women and Children's Hospital on May 28, 2022 was selected for the study. Clinical data were collected, and peripheral blood samples from the child and her parents were obtained for genomic DNA extraction. Whole exome sequencing (WES) was performed to screen for pathogenic variants. Candidate variants were validated via Sanger sequencing and subjected to bioinformatic analysis. This study was approved by the Medical Ethics Committee of Ningbo Women and Children's Hospital (Ethics No. EC2020-014).
RESULTS:
The child was a 7-year-old female with a diagnosis of epilepsy. WES revealed that she has carried a heterozygous missense variant in the COL4A1 gene: c.1792G>A (p.Gly598Ser). Sanger sequencing confirmed that her parents both had the wild-type genotype for this variant. Based on American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants, the variant were predicted to be a likely pathogenic (PS2+PM1+PM2_Supporting+PP3). Bioinformatics predicted that amino acid 598 was highly conserved in different species, formed hydrogen bond with Asp599 after becoming Ser598.
CONCLUSION
The heterozygous missense variant of the COL4A1 gene c.1792T>C (p.G598S) could be the pathogenic cause of this child with Brain small vessel disease 1 with ocular anomalies.

OBJECTIVE:
To explore the clinical characteristics and genetic etiology of a patient with Fliedner-Zweier syndrome (FZS).
METHODS:
A pregnant woman who was diagnosed with FZS at the Affiliated Women and Children's Hospital of Ningbo University in November 2023 for "intellectual disability, epilepsy, delayed language development and facial abnormalities" was selected as the study subject. Peripheral blood samples were collected from the woman and her husband, whilst amniotic fluid sample was obtained from the fetus. Following extraction of genomic DNA, whole-exome sequencing (WES) and chromosomal karyotyping analysis were performed. Candidate variant was validated by Sanger sequencing. Pathogenicity of the variant was classified based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: EC2023-094).
RESULTS:
The proband, a 23-year-old woman, was at 19+2 weeks of gestation and had a history of epilepsy, mild intellectual disability, delayed language development, and subtle facial dysmorphism. Chromosomal analysis showed the she has a normal karyotype. WES revealed that the woman and her fetus both harbored a heterozygous c.1489C>T (p.Gln497Ter) nonsense variant of the SCAF4 gene, which was verified by Sanger sequencing as de novo. Based on the ACMG guidelines, the variant was classified as pathogenic (PVS1+PM2_supporting+PS2_supporting). According to pre-set search strategy, five articles were retrieved. Together with the patient in this study, a total of 69 FZS patients were involved (including 7 from China). The main clinical features have included intellectual disability, epilepsy, behavioral abnormalities, and facial dysmorphism.
CONCLUSION
The heterozygous c.1489C>T (p.Gln497Ter) variant of the SCAF4 gene probably underlyay the FZS in this patient. Above finding has expanded the mutational spectrum of the SCAF4 gene.
