Generation of induced pluripotent stem cells named SMBCi019-A from a methylmalonic acidemia patient carrying the MMACHC mutations


Methylmalonic acidemia(MMA) is an autosomal recessive hereditary disease caused by methylmalonyl-CoA mutase defect or its coenzyme cobalamin metabolism defect. The mutation of the MMACHC gene leads to metabolic disorder of coenzyme cobalamin, resulting in abnormal accumulation of methylmalonic acid, and finally leads to impairment of multiple organs' functions. Here we generated an induced pluripotent stem cells (iPSCs) line named SMBCi019-A, using urine cells (UCs) derived from a 10-year-old male MMA patient who carried two heterozygous gene mutations in MMACHC c.438G > A (p.w146x) and c.609G > A (p.w203x). The generated iPSCs retained the mutations can function as a cellular model of MMA. Copyright © 2022 The Authors. Published by Elsevier B.V. All rights reserved.
