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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09565723).
• BP6: Variant 9-137192192-G-T is Benign according to our data. Variant chr9-137192192-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 1567018.Status of the report is criteria_provided_single_submitter, 1 stars.
