Summaries for Masp2 Deficiency

OMIM : 57 MASP2 deficiency, classically defined as MASP2 protein level of less than 100 ng/ml, occurs in about 4% of Caucasians and up to 18% of some African populations. Some MASP2-deficient individuals have increased risk of infection or autoimmune disease, but most are asymptomatic. MASP2 plays a role in activation of the lectin pathway of the complement system; deficiency may thus lead to defects in the complement system (summary by Thiel et al., 2007 and Sokolowska et al., 2015). For a discussion of genetic heterogeneity of lectin complement activation pathway defects, see LCAPD1 (614372). (613791)

MalaCards based summary : Masp2 Deficiency, also known as lcapd2, is related to frontotemporal dementia. An important gene associated with Masp2 Deficiency is MASP2 (Mannan Binding Lectin Serine Peptidase 2). Related phenotypes are systemic lupus erythematosus and complement deficiency

UniProtKB/Swiss-Prot : 75 MASP2 deficiency: A disorder that results in autoimmune manifestations, recurrent severe infections, and chronic inflammatory disease.
