Monogenic hearing loss
Gene: GOSR2
Four children from two sibships from an extended consanguineous Palestinian family were reported with congenital profound hearing loss, whereas the parents of both sibships are first cousins with normal hearing. The families reported occasional febrile seizures in infancy for each of the deaf children, but these did not persist into adolescence. These affected children were identified with autosomal recessive GOSR2 variant, c.1A > C, p.Met1Leu. This variant appeared once in the gnomAD database, as a heterozygote, and not in any of ~2000 in-house controls of Palestinian ancestry.
All previously reported cases with biallelic GOSR2 variants had normal hearing and hence the differences in translation efficiency due to the effect of this variant may be responsible for this hearing loss phenotype (PMID:37074134).
