Neutral lipid storage disease

Disease definition

Neutral lipid storage disease (NLSD) refers to a group of diseases characterized by a deficit in the degradation of cytoplasmic triglycerides and their accumulation in cytoplasmic lipid vacuoles in most tissues of the body. The group is heterogeneous: currently cases of NLSD with icthyosis (NLSDI/Dorfman-Chanarin disease; see this term) and NLSD with myopathy (NLSDM/neutral lipid storage myopathy; see this term) can be distinguished.
