Genes affected

TXNDC15 (HGNC:20652): (thioredoxin domain containing 15) This gene encodes a member of the thioredoxin superfamily. Members of this family are characterized by a conserved active motif called the thioredoxin fold that catalyzes disulfide bond formation and isomerization. [provided by RefSeq, Apr 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.031624645).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000164 (24/1461874) while in subpopulation AMR AF= 0.000514 (23/44724). AF 95% confidence interval is 0.000351. There are 0 homozygotes in gnomad4_exome. There are 6 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.317G>C (p.S106T) alteration is located in exon 2 (coding exon 2) of the TXNDC15 gene. This alteration results from a G to C substitution at nucleotide position 317, causing the serine (S) at amino acid position 106 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 106 of the TXNDC15 protein (p.Ser106Thr). This variant is present in population databases (rs758309291, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with TXNDC15-related conditions. ClinVar contains an entry for this variant (Variation ID: 2180878). 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 tolerated. 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. -
