Comment on list classification: Variants in STIM1 result in activation of ORAI1 peptide function which was predicted result in increased ORAI1 (610277)-mediated calcium influx in Stormorken syndrome 185070 (PMID 24619930). However, variants in ORAI1 have not been associated with this or other bleeding disorders. PMID: 26469693 states: “By contrast, autosomal dominant gain-of-function mutations in these genes [ORAI1 and STIM1] result in constitutive CRAC channel activation, SOCE, and increased intracellular Ca2+ levels that are associated with an overlapping spectrum of diseases, including non-syndromic tubular aggregate myopathy (TAM) and York platelet and Stormorken syndromes, two syndromes defined, besides myopathy, by thrombocytopenia, thrombopathy, and bleeding diathesis.”Created: 6 Feb 2018, 1:46 p.m.
