dbSNP rs146159479: TMPRSS3:p.Arg80His (chr21-42389012-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 3P and 9B. PM5PP2BP4_StrongBP6BS1

The NM_001256317.3(TMPRSS3):c.239G>A(p.Arg80His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000186 in 1,614,124 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict 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. R80C) has been classified as Likely pathogenic.

Genes affected

TMPRSS3 (HGNC:11877): (transmembrane serine protease 3) This gene encodes a protein that belongs to the serine protease family. The encoded protein contains a serine protease domain, a transmembrane domain, an LDL receptor-like domain, and a scavenger receptor cysteine-rich domain. Serine proteases are known to be involved in a variety of biological processes, whose malfunction often leads to human diseases and disorders. This gene was identified by its association with both congenital and childhood onset autosomal recessive deafness. This gene is expressed in fetal cochlea and many other tissues, and is thought to be involved in the development and maintenance of the inner ear or the contents of the perilymph and endolymph. This gene was also identified as a tumor-associated gene that is overexpressed in ovarian tumors. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr21-42389013-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 228296.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 41 curated pathogenic missense variants (we use a threshold of 10). The gene has 12 curated benign missense variants. Trascript score misZ: 0.22926 (below the threshold of 3.09). GenCC associations: The gene is linked to hearing loss, autosomal recessive, autosomal recessive nonsyndromic hearing loss 8, nonsyndromic genetic hearing loss.

BP4

Computational evidence support a benign effect (MetaRNN=0.01501891).

BP6

Variant 21-42389012-C-T is Benign according to our data. Variant chr21-42389012-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 179855.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000187 (274/1461848) while in subpopulation EAS AF = 0.0035 (139/39700). AF 95% confidence interval is 0.00303. There are 1 homozygotes in GnomAdExome4. There are 155 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
