Genes affected

TMX2 (HGNC:30739): (thioredoxin related transmembrane protein 2) This gene encodes a member of the disulfide isomerase (PDI) family of endoplasmic reticulum (ER) proteins that catalyze protein folding and thiol-disulfide interchange reactions. The encoded protein has an N-terminal ER-signal sequence, a catalytically active thioredoxin domain, one transmembrane domain and a C-terminal ER-retention sequence. This protein is enriched on the mitochondria-associated-membrane of the ER via palmitoylation of two of its cytosolically exposed cysteines. [provided by RefSeq, Jan 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM1

In a chain Thioredoxin-related transmembrane protein 2 (size 247) in uniprot entity TMX2_HUMAN there are 19 pathogenic changes around while only 0 benign (100%) in ENST00000278422.9

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.04124987).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000857 (13/151652) while in subpopulation EAS AF= 0.00135 (7/5170). AF 95% confidence interval is 0.000635. There are 1 homozygotes in gnomad4. There are 4 alleles in male gnomad4 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.334A>G (p.M112V) alteration is located in exon 3 (coding exon 3) of the TMX2 gene. This alteration results from a A to G substitution at nucleotide position 334, causing the methionine (M) at amino acid position 112 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
