In these, the final diagnoses were immune checkpoint inhibitor related myofasciitis (n = 1; anti-SRP), primary Raynaud’s phenomenon (n = 1; anti-TIF1γ), fibromyalgia (n = 1; anti-Mi2B), statin-related toxic myopathy (n = 1; anti-Mi2B with anti-SAE1), polymyalgia rheumatica (n = 2; anti-OJ, anti-PL7), familial amyloidosis (n = 1; anti-SAE1), and unclear (n = 8; anti-SRP [n = 3], anti-TIF1γ [n = 2], antiPL7 with anti-SRP [n = 1], anti-Mi2A with anti-SRP [n = 1], anti-PL12 with anti-SRP [n = 1]). This evidence concerns the gene UCN2 and fibromyalgia.
