'''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>.

== Relevance ==
 
B2M is used as a marker for certain types of blood cell cancer.  It can indicate the spread and severity of myeloma.
