Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_001128228.3(TPRN):​c.2111G>A​(p.Arg704His) variant causes a missense change. The variant allele was found at a frequency of 0.0000868 in 1,613,582 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R704C) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.057493925).
BP6
Variant 9-137192137-C-T is Benign according to our data. Variant chr9-137192137-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1195124.
BS1
Variant frequency is greater than expected in population afr. GnomAdExome4 allele frequency = 0.0000691 (101/1461254) while in subpopulation AFR AF = 0.00137 (46/33480). AF 95% confidence interval is 0.00106. There are 0 homozygotes in GnomAdExome4. There are 43 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
