Abstract

Mutations in the CEACAM6 gene were first described as causing autosomal dominant nonsyndromic hearing loss, but two splice-altering variants have been recently described as causing autosomal recessive nonsyndromic hearing loss. We describe the novel and extremely rare loss-of-function variant c.436 C > T/p.(Arg146Ter) in the CEACAM16 gene segregating with post-lingual progressive autosomal recessive hearing loss. This variant is predicted to significantly reduce the size of the wild type protein. Our results give additional support that loss-of-function variants in CEACAM16 cause autosomal recessive hearing loss in humans. (AU)
