摘要

The broad spectrum of causal variants in the newly discoveredGIPC3gene is well reflected in worldwide studies. Except for one missense variant, none of the reported variants had reoccurred, thus reflecting the intragenic heterogeneity. We screened all the six coding exons ofGIPC3gene in a large cohort of 177 unrelated prelingual hearing impaired after excluding the commonGJB2,GJB6nuclear and A1555G mitochondrial variants. We observed a single homozygous pathogenic frameshift variant c.685dupG (p.A229GfsX10), accounting for a low incidence (0.56%) ofGIPC3variants in south Indian population.GIPC3being a rare gene as a causative for deafness, the allelic spectra perhaps became much more diverse from population to population, thus resulting in a minimal recurrence of the variants in our study, that were reported by authors from other parts of the globe.
