Abstract:
OBJECTIVE:To detect potential variation in an ethnic Han Chinese family affected with late-onset lipid storage myopathy.
METHODS:Next generation sequencing (NGS) was used to screen disease-related genes in the proband. Suspected mutation was validated with PCR and Sanger sequencing in two patients, their father, and 100 healthy controls.
RESULTS:Heterozygous c.770A>G (p.Tyr257Cys) and c.1395dupT (p.Gly466Tryfs) mutation were detected in the two patients. Their father was found to be heterozygous for the c.770A>G (p.Tyr257Cys) mutation, while the c.1395dupT (p.Gly466Tryfs) variation was not reported previously and not found among the healthy controls.
CONCLUSION:Mutations of the ETFDH gene probably underlie the pathogenesis in this family. The novel c.1395dupT (p.Gly466Tryfs) has enriched the mutation spectrum of EDFDH gene.
