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]

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.012%). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 12393794, 23958653). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.77; 3Cnet: 0.47). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000046114 / PMID: 11424922). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 11424922, 28566687). A different missense change at the same codon (p.Arg109Gln) has been reported to be associated with TMPRSS3 related disorder (PMID: 24853665). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with autosomal recessive deafness 8/10 (MIM#601072). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to tryptophan. (I) 0252 - This variant is homozygous. (I) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (v2 & v3: 47 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2 & v3: 42 heterozygotes, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change.

Variant summary: TMPRSS3 c.325C>T (p.Arg109Trp) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00013 in 251350 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in TMPRSS3 causing Deafness, Autosomal Recessive 8, allowing no conclusion about variant significance. c.325C>T has been reported in the literature in multiple individuals affected with Deafness, Autosomal Recessive 8 and this variant co-segregated with this disease (Ben-Yosef_2001). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function and this variant affected the TMPRSS3 protein function (Lee_2003). The following publications have been ascertained in the context of this evaluation (PMID: 11424922, 12920079). ClinVar contains an entry for this variant (Variation ID: 46114). Based on the evidence outlined above, the variant was classified as pathogenic. -

Identified with a second variant in additional patients with sensorineural hearing loss in published literature (PMID: 28566687); Published functional studies demonstrate a damaging effect due to failure to undergo proteolytic cleavage and activate the epithelial sodium channel (PMID: 12920079, 16524950, 12393794); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 12393794, 28246597, 16524950, 29937438, 18928407, 29072634, 24526180, 31589614, 32860223, 34426522, 34519870, 34868270, 36871673, 23958653, 35961784, 37331337, 11424922, 12920079, 28566687) -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 109 of the TMPRSS3 protein (p.Arg109Trp). This variant is present in population databases (rs201632198, gnomAD 0.2%). This missense change has been observed in individual(s) with deafness (PMID: 11424922). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 46114). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects TMPRSS3 function (PMID: 12920079). This variant disrupts the p.Arg109 amino acid residue in TMPRSS3. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 24853665; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -

The Arg109Trp variant in TMPRSS3 has been reported in one family with hearing lo ss in which the variant segregated with disease (homozygous) in 3 affected and w as heterozygous in 5 unaffected family members, and was absent from 159 controls (318 chromosomes) (Ben-Yosef 2001). Our laboratory has also identified this var iant as a compound heterozygote with other pathogenic mutations in two probands with hearing loss. And finally, two studies have reported that the Arg109Trp var iant leads to a protein product that is only partially active (Guipponi 2002, An dreasen 2006). In summary, this variant meets our criteria to be classified as p athogenic. -
