Genes affected

SLC40A1 (HGNC:10909): (solute carrier family 40 member 1) The protein encoded by this gene is a cell membrane protein that may be involved in iron export from duodenal epithelial cells. Defects in this gene are a cause of hemochromatosis type 4 (HFE4). [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 2-189561142-C-CT is Benign according to our data. Variant chr2-189561142-C-CT is described in ClinVar as [Likely_benign]. Clinvar id is 333155.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00271 (413/152290) while in subpopulation AFR AF= 0.00888 (369/41568). AF 95% confidence interval is 0.00813. There are 1 homozygotes in gnomad4. There are 228 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 413 AD gene.
