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]

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jan 04, 2019	The p.Glu646Lys variant in TPRN has not been previously reported in individuals with hearing loss but has been identified in 0.02% (3/17194) of East Asian chrom osomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID 440352). Computational prediction tools and co nservation analysis do not provide strong support for or against an impact to th e protein. In summary, the clinical significance of the p.Glu646Lys variant is u ncertain. ACMG/AMP Criteria applied: PM2_Supporting. -
