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 Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_024715.4.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 5-134893571-CCAGTTTGGCCCCTCA-C is Pathogenic according to our data. Variant chr5-134893571-CCAGTTTGGCCCCTCA-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 266074.Status of the report is no_assertion_criteria_provided, 0 stars.
