Hereditary deafness is a genetically heterogeneous phenotype for which more than 100 genomic loci have been identified thus far. By analysis of a consanguineous Palestinian family, GPSM2 was recently discovered to be the cause of autosomal recessive non-syndromic hearing loss DFNB82. Here, we report a second truncating mutation, GPSM2 p.Q562X, identified via autozygosity mapping in a consanguineous Turkish family. This report provides evidence for allelic heterogeneity of GPSM2 and confirms its causative role for non-syndromic deafness.
