Genes affected

TXN (HGNC:12435): (thioredoxin) The protein encoded by this gene acts as a homodimer and is involved in many redox reactions. The encoded protein is active in the reversible S-nitrosylation of cysteines in certain proteins, which is part of the response to intracellular nitric oxide. This protein is found in the cytoplasm. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.25).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0127 (1932/152332) while in subpopulation NFE AF = 0.0219 (1491/68030). AF 95% confidence interval is 0.021. There are 28 homozygotes in GnomAd4. There are 857 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 28 gene
