Popis: To explore the genetic basis for a Chinese pedigree affected with non-syndromic hearing loss (NSHL).Commercialized gene chip was applied to detect common mutations associated with congenital deafness. Whole exome sequencing was carried out for patients for whom gene chip yielded a negative result. Candidate variants were verified by Sanger sequencing.Two patients from the pedigree were discovered to carry compound heterozygous variants of the TRIOBP gene, namely c.3299CA and c.5185-2AG. Their parents had normal hearing and were both heterozygous carriers of the above variants. Both variants had co-segregated with the disease phenotype in the pedigree and were unreported previously.Pathogenic variants of the TRIOBP gene comprise an important factor for NSHL. The novel c.5185-2AG and c.3299CA variants discovered in this study have enriched the mutational spectrum of the TRIOBP gene and enabled molecular diagnosis and genetic counseling for the family.
