摘要: ABSTRACT: Causative genes have been identified only in four types oflipid storage myopathies (LSMs): SLC22A5 for primary carnitine deficiency(PCD); ETFA , ETFB and ETFDH multiple acyl-coenzyme A dehydroge-nation deficiency (MADD); PNPLA2 neutral lipid disease withmyopathy (NLSDM); ABHD5 withichthyosis. However, the frequency of these LSMs has not determined.We found mutations 9 37 LSM patients (24%): 3 ;4inMADD-associated genes; 2 . This low suggeststhe existence other causative Muscle coenzyme Q 10 levels werenormal or mildly reduced two MADD patients, indicating that ETFDHmutations may always be associated with CoQ deficiency. The 2patients had progressive, non-episodic muscledisease rimmed vacuoles. suggests there is a different patho-mechanism from LSMs. Nerve 39: 333–342, 2009 CLINICAL AND GENETIC ANALYSISOF LIPID STORAGE MYOPATHIES
