In all subjects, carriers of at least one polymorphic CALB2 rs889704 A allele had lower calretinin than carriers of two wild-type alleles in the dominant model (P = 0.036), but no significant differences were observed if subjects without MM and MM patients were evaluated separately (P = 0.069 and 0.441, respectively). Here, CALB2 is linked to Miyoshi myopathy.
