Variant summary

Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM2PM5PP2

The NM_001256317.3(TMPRSS3):c.239G>T(p.Arg80Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,614,006 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. 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: Uncertain_significance. The variant received 5 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

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.
