Evidence/Notes:

MPIG6B was first reported in relation to autosomal recessive Thrombocytopenia, anemia, and myelofibrosis in 2017 (Melhem et al., 2017; PMID: 27743390). At least 5 unique variants (e.g. missense, splicing, nonsense, and frameshift) have been reported in humans. Evidence supporting this gene disease relationship includes case-level data, segregation data, and experimental data. Variants in this gene have been reported in at least 6 probands in 3 publications (PMIDs: 27743390, 29898956, 31276734). Variants in this gene segregated with disease in 7 additional family members. This gene-disease association is supported by its enhanced expression in lymphoid tissue (PMID: 17311996), its inhibitory biochemical function in platelet activation (PMID: 17311996), and mouse models (including knockout, knock-in, megakaryocyte specific conditional knockout, and humanized models) which recapitulate human disease (PMIDs: 23112346, 23509158, 29891536, 29898956). In summary, MPIG6B is definitively associated with autosomal recessive Thrombocytopenia, anemia, and myelofibrosis.
