Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 5P and 1B. PM1PM2PP2BP4
The NM_001256317.3(TMPRSS3):c.298G>C(p.Asp100His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,614,096 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 Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. D100D) has been classified as Likely benign.

not specified Uncertain:1
The p.Asp100His variant in TMPRSS3 has been reported by our laboratory in 1 Cauc asian individual with hearing loss; however, a variant affecting the remaining c opy of TMPRSS3 was not identified in this individual (LMM unpublished data). It has also been identified in 1/11568 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs397517374). Computatio nal prediction tools and conservation analysis suggest that the p.Asp100His vari ant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Asp10 0His variant is uncertain. -
not provided Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 100 of the TMPRSS3 protein (p.Asp100His). This variant is present in population databases (rs397517374, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TMPRSS3-related conditions. ClinVar contains an entry for this variant (Variation ID: 46110). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TMPRSS3 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
