Sarcotubular myopathy (OMIM 268950) is a rare autosomal recessive myopathy first
described in two Hutterite brothers from South Dakota and in two non‐Hutterite brothers from
Germany. We report that sarcotubular myopathy (STM) is caused by mutation in TRIM32, the
gene encoding the tripartite motif‐containing protein 32. TRIM32 was found to be the gene

Abstract
Sarcotubular myopathy (OMIM 268950) is a rare autosomal recessive myopathy first described in two Hutterite brothers from South Dakota and in two non‐Hutterite brothers from Germany. We report that sarcotubular myopathy (STM) is caused by mutation in TRIM32, the gene encoding the tripartite motif‐containing protein 32. TRIM32 was found to be the gene mutated in limb girdle muscular dystrophy type 2H (LGMD2H [OMIM 254110]), a disorder that has been confined to the Hutterite population. The TRIM32 mutation found in the STM patients is identical to the causative mutation for LGMD2H (D487N), Haplotype analysis shows that the disease chromosomes share common ancestry.
