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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-134887800-G-GC is Pathogenic according to our data. Variant chr5-134887800-G-GC is described in ClinVar as [Pathogenic]. Clinvar id is 1687009.Status of the report is no_assertion_criteria_provided, 0 stars.
