The protein encoded by this gene is a membrane protein that is similar to MHC class I-type proteins and associates with beta2-microglobulin (beta2M). It is thought that this protein functions to regulate iron absorption by regulating the interaction of the transferrin receptor with transferrin. The iron storage disorder, hereditary haemochromatosis, is a recessive genetic disorder that results from defects in this gene. At least nine alternatively spliced variants have been described for this gene. Additional variants have been found but their full-length nature has not been determined.,HFE,HFE1,HH,HLA-H,MVCD7,TFQTL2,Signal Transduction,Endocrine & Metabolism,Neuroscience,Neurodegenerative Diseases Markers,Other Neurological disorders,Stem Cells,Hematopoietic Progenitors,Amyotrophic lateral sclerosis-ALS,HFE
