Recently, mutations in PNPLA2 encoding adipose triglyceride lipase (ATGL) were reported to underlie a neutral lipid storage disease (NLSD) subgroup characterized by mild myopathy and the absence of ichthyosis. In the present study a novel homozygous PNPLA2 mutation c.475_478dupCTCC (p.Gln160ProfsX19) in the patatin domain, the ATGL active site, was detected in a woman with NLSD and severe myopathy. The present results suggest that a premature truncation mutation in the patatin domain causes NLSD with severe myopathy.
