ABSTRACT
OBJECTIVE:
To explore the genetic etiology of Vici syndrome in a Chinese family.METHODS:
Whole exome sequencing (WES) technology was used to detect gene variants in a fetus of abnormal ultrasonic structure without abnormalities in routine chromosome karyotype analysis and SNP-array. Sanger sequencing and bioinformatics prediction were performed for the suspected variants of the fetus and parents.RESULTS:
The fetus and the elder sister have carried c. 2427delC (p.T809fs) and c.1886A>T (p.E629V) compound heterozygous variants of the EPG5 gene, which were respectively inherited from their mother and father. Neither variant was reported previously. According to ACMG guidelines, the c.2427delC variant was predicted as pathogenic, while the c.1886A>T variant was of uncertain significance. PolyPhen-2 and PROVEAN software indicated that c.1886A>T variant was probably damaging.CONCLUSION:
The c.2427delC and c.1886A>T variants of the EPG5 gene probably underlie the pathogenesis of the Vici syndrome in this family. Above finding has enriched the variational spectrum of EPG5 gene and provided a basis for genetic counseling and prenatal diagnosis for the family.
