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 -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.004536718).
BP6
Variant 9-137199451-G-A is Benign according to our data. Variant chr9-137199451-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 377178.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=1}. Variant chr9-137199451-G-A is described in Lovd as [Likely_benign].
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00161 (246/152356) while in subpopulation NFE AF= 0.00256 (174/68016). AF 95% confidence interval is 0.00225. There are 0 homozygotes in gnomad4. There are 109 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 4 AR gene
