Abstract

Hereditary hearing loss (HHL) is an extremely heterogeneous disorder with autosomal dominant, recessive, and X-linked forms. Here, we described an Italian pedigree affected by HHL but also prostate hyperplasia and increased ratio of the free/total PSA levels, with the unusual and extremely rare Y-linked pattern of inheritance. Using exome sequencing we found a missense variant (r.206A>T leading to p.Asp69Val) in the TBL1Y gene. TBL1Y is homologous of TBL1X, whose partial deletion has described to be involved in X-linked hearing loss. Here, we demonstrate that it has a restricted expression in adult human cochlea and prostate and the variant identified induces a lower protein stability caused by misfolded mutated protein that impairs its cellular function. These findings indicate that TBL1Y could be considered a novel candidate for HHL.
