Genes affected

TPRN (HGNC:26894): (taperin) This locus encodes a sensory epithelial protein. It was defined by linkage analysis in three Pakistani families to lie between D9S1818 (centromeric) and D9SH6 (telomeric). Mutations at this locus have been associated with autosomal recessive deafness. [provided by RefSeq, Oct 2010]

The p.Ala695Thr variant in TPRN has been previously reported in 1 family with no nsyndromic hearing loss who also carried a homozygous variant in another gene th at was a likely explanation for their hearing loss (Diaz-Horta 2012). The p.Ala6 95Thr variant is absent from large population studies. Computational prediction tools and conservation analysis suggest that this variant may impact the protein , though this information is not predictive enough to determine pathogenicity. I n summary, the clinical significance of the p.Ala695Thr variant is uncertain. -
