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]

SLC40A1 Gene-Disease associations (from GenCC):

• hemochromatosis type 4

  Inheritance: AD, AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Genomics England PanelApp, Labcorp Genetics (formerly Invitae), G2P, PanelApp Australia, Orphanet, Ambry Genetics

ACMG classification
