APOE and inclusion body myositis: Interestingly, an intronic polymorphism (rs10527454, described as ‘rs10524523’ in currently published papers) in a gene called “translocase of outer mitochondrial membrane 40” (TOMM40) which is adjacent to and in linkage disequilibrium with the APOE locus on chromosome 19 [46], together with the APOE genotypes, has been revealed to affect IBM disease susceptibility [47].
