neutral lipid storage disease (Monarch Disease Ontology identifier MONDO_0015611) (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) and NLSD with myopathy (NLSDM/neutral lipid storage myopathy) can be distinguished. Also known as: lipidosis with triglyceride storage disease.
