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

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
This place is a probable branch point but likely benign (scored 0 / 10). Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BP6
Variant 9-137192205-T-C is Benign according to our data. Variant chr9-137192205-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 1206635.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0015 (229/152288) while in subpopulation AFR AF= 0.00522 (217/41548). AF 95% confidence interval is 0.00465. There are 1 homozygotes in gnomad4. There are 116 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
