This retrospective study included 356 patients with hepatitis B virus-related liver cirrhosis after applying inclusion and exclusion criteria among 661 patients.

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.
