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]

Feb 14, 2023

The c.2062G>A (p.V688M) alteration is located in exon 3 (coding exon 3) of the TPRN gene. This alteration results from a G to A substitution at nucleotide position 2062, causing the valine (V) at amino acid position 688 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
