When transcripts matter: delineating between non-syndromic hearing loss DFNB32 and hearing impairment infertile male syndrome (HIIMS).

ABSTRACT: Mutations in the CDC14A (Cell Division-Cycle 14A) gene, which encodes a conserved dual-specificity protein tyrosine phosphatase, have been identified as a cause of autosomal recessive non-syndromic hearing loss (DFNB32) and hearing impairment infertility male syndrome (HIIMS). We used next-generation sequencing to screen six deaf probands from six families segregating sensorineural moderate-to-profound hearing loss. Data analysis and variant prioritization were completed using a custom bioinformatics pipeline. We identified three homozygous loss of function variants (p.Arg345Ter, p.Arg376Ter, and p.Ala451Thrfs*43) in the CDC14A gene, segregating with deafness in each family. Of the six families, four segregated the p.Arg376Ter mutation, one family segregated the p.Arg345Ter mutation and on
