==Disease==

[[http://www.uniprot.org/uniprot/B2MG_HUMAN B2MG_HUMAN]] Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:[http://omim.org/entry/241600 241600]]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.<ref>PMID:16549777</ref> Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis.<ref>PMID:3532124</ref><ref>PMID:1336137</ref><ref>PMID:7554280</ref><ref>PMID:4586824</ref><ref>PMID:8084451</ref><ref>PMID:12119416</ref><ref>PMID:12796775</ref><ref>PMID:16901902</ref><ref>PMID:16491088</ref><ref>PMID:17646174</ref><ref>PMID:18835253</ref><ref>PMID:18395224</ref><ref>PMID:19284997</ref>
