Objective:To explore the prenatal and postnatal features and genetic characteristics of patients with Lymphedema-Distichiasis syndrome (LDS) due to variants of FOXC2 gene. Methods:A retrospective analysis was carried out on the phenotypic information, fetal ultrasound image, and genetic testing of two Chinese pedigrees diagnosed at the Third Affiliated Hospital of Zhengzhou University. A literature review was also carried out by searching the China National Knowledge Infrastructure (CNKI), Wanfang Database, and PubMed databases dated from January 2010 to June 2024 using keywords "Lymphedema-Distichiasis syndrome" and " FOXC2". This study has been approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethic No.2021-046-01). Results:Neither family was found to harbor chromosomal aneuploidy or pathogenic CNVs larger than 100 kb. The fetuses from pedigree 1 and pedigree 2 were respectively found to be heterozygous for a c. 361C>T (p.R121C) variant and a c. 168C>A (p.Y56*) variant of the FOXC2 gene. Both variants were paternally derived. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variants were classified as pathogenic and likely pathogenic, respectively. Literature search has identified 20 articles, and combined with our cases, a total of 117 patients were identified. Among them, 13 had shown prenatal phenotypes, primarily with increased nuchal translucency (NT) (12/13), urinary abnormalities (5/12), and fetal edema (4/13). Postnatal phenotypes were observed in 110 cases, mainly as distichiasis (87/110) and lymphedema (73/110). Only 6 cases had both prenatal and postnatal phenotypes. A total of 32 genetic variants were identified. Conclusion:The primary prenatal manifestations of LDS include increased NT, fetal edema, pleural and abdominal effusion, and separation of renal collecting system. Postnatal phenotypes are primarily characterized by lymphedema, distichiasis, and spinal extradural arachnoid cysts. Discovery of the c. 168C>A variant has expanded the spectrum of FOXC2 gene mutations in China.

OBJECTIVE:
To explore the clinical phenotype and genetic variants of a fetus with Glutaracidemia type II C (GA II C).
METHODS:
Clinical data of a 32-year-old pregnant woman and her fetus with GA II C diagnosed at the Third Affiliated Hospital of Zhengzhou University in December 2021 due to the enlargement and enhanced echo of the kidneys and oligohydramnios fluid at 17 weeks were analyzed retrospectively. Amniotic fluid sample of the fetus and peripheral blood samples of the couple were collected for whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing. Copy number variation (CNV) was detected by using low-coverage whole genome sequencing (CNV-seq).
RESULTS:
At 18 weeks' gestation, ultrasound revealed that the fetus had enlargement and enhanced echo of the kidneys along with no echo of renal parenchymal tubular fissure and oligohydramnios. MRI at 22 weeks' gestation confirmed that both kidneys were enlarged with uniformly increased abnormal T2 signal and decreased DWI signal. The volume of both lungs was small, with slightly higher T2 signal. No CNV was detected in the fetus. WES revealed that the fetus has harbored compound heterozygous variants of the ETFDH gene, namely c.1285+1G>A and c.343_344delTC, which were inherited from its father and mother, respectively. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were classified as pathogenic (PVS1+PM2_Supporting+PS3_Supporting; PVS1+PM2_Supporting+PM3).
CONCLUSION
The c.1285+1G>A and c.343_344delTC compound heterozygous variants of the ETFDH gene probably underlay the disease in this fetus. Type II C glutaric acidemia may manifest as bilateral kidney enlargement with enhanced echo and oligohydramnios. Discovery of the c.343_344delTC has enriched the spectrum of ETFDH gene variants.

Chinese Journal of Medical Genetics 2023;40(3):332-336
OBJECTIVE:
To explore the clinical phenotypes and genetic diagnosis of 2 sporadic cases for cleidocranial dysplasia.
METHODS:
The clinical data of two cases of CCD admitted to the Third Affiliated Hospital of Zhengzhou University on December 16, 2021 and December 9, 2021 were analyzed retrospectively, and the whole exome sequencing (WES), chromosome microarray analysis and copy number variation sequencing were performed.
RESULTS:
The main ultrasonographic findings of the fetus had included poorly calcified skull bones, budging of parieto-occipital area, compression and deformation of skull, and loss of nasal bone. The infant's clinical phenotypes included delayed closure of anterior fontanelle, recurrent respiratory tract infection, growth retardation, and clavicular hypoplasia. By WES analysis, the fetus was found to harbor a heterozygous c.911_914delinsTTT variant of the RUNX2 gene, whilst the infant was found to harbor a heterozygous c.1008delT variant of the RUNX2 gene. Both variants were verified by Sanger sequencing to have occurred de novo.
CONCLUSION
For sporadic cases featuring cleidocranial dysplasia, prenatal ultrasonography is particularly important. Hypoplastic clavicle, skull calcification and nasal bone absence are the main features. Diagnosis should also be suspected for infants featuring growth retardation, recurrent respiratory tract infections and clavicular dysplasia. The identification of the c.911_914delinsTTT and c.1008delT variants of the RUNX2 gene has facilitated genetic counseling and prenatal diagnosis, and also expanded the mutational spectrum of the RUNX2 gene.
