Genes affected

STEAP3 (HGNC:24592): (STEAP3 metalloreductase) This gene encodes a multipass membrane protein that functions as an iron transporter. The encoded protein can reduce both iron (Fe3+) and copper (Cu2+) cations. This protein may mediate downstream responses to p53, including promoting apoptosis. Deficiency in this gene can cause anemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

STEAP3-AS1 (HGNC:41053): (STEAP3 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0147 (2237/152094) while in subpopulation AFR AF = 0.0514 (2133/41482). AF 95% confidence interval is 0.0496. There are 59 homozygotes in GnomAd4. There are 1061 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High AC in GnomAd4 at 2237 AD,Unknown gene.
