Mu-heavy chain disease (mu-HCD) is a type of HCD characterized by the production of incomplete monoclonal mu-heavy chains without associated light chains. The clinical presentation resembles that of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).
Biomarker and diagnostic research for mu-heavy chain disease has been reported in the published literature.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for mu-heavy chain disease.
3 publications have been identified in PubMed for mu-heavy chain disease. Research spans Case Report / Case Series (67%) and Diagnostic / Biomarker (33%).
