[[Beta-2 microglobulin]] ('''B2M''') is a component of MHC class I system. B2M associates with MHC class I α chain, CD1 and Qa. Loss of B2M function causes iron excess. <ref>PMID:21131979</ref> For more details, see: [[Human beta two microglobulin]] and [[Molecular playground/beta 2 microglobulin]].

'''Beta-2 microglobulin''' (B2M) is a component of MHC class I system. B2M associates with MHC class I α chain, CD1 and Qa. Loss of B2M function causes iron excess.

Elevated B2M levels are found in patients of liver cirrhosis<ref>PMID:3884477</ref> and hepatitis<ref>PMID:29221492</ref>. Dialysis-associated amyloidosis is a serious complication in chronic dialysis patients. It is caused by B2M fibrils amyloid deposits<ref>PMID:10737162</ref>.
