A rare form of syndromic dilated cardiomyopathy (DCM) is the Alström syndrome (AS) [OMIM 203800] (prevalence 1.4 cases per 1,000,000), a multisystem disorder, inherited as autosomal recessive trait, caused by mutations in the ALMS1 (Zmyslowska et al., 2016) (OMIM 606,844). Here, ALMS1 is linked to Alstrom syndrome.
