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]

p.Pro662Pro in Exon 3 of TPRN: This variant is not expected to have clinical sig nificance because it does not alter an amino acid residue, is not located within the splice consensus sequence. It has been identified in 1/9646 of African chro mosomes and 1/63686 of European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs373509671). -
