Generation of induced pluripotent stem cells (iPSCs) from a hereditary spastic paraplegia patient carrying a homozygous R486C mutation in CYP7B1 (SPG5)

Abstract

Skin fibroblasts were obtained from a 47-year-old hereditary spastic paraplegia patient carrying a homozygous mutation R486C in CYP7B1 (Cytochrome P450, Family 7, Subfamily B, Polypeptide 1), responsible for causing hereditary spastic paraplegia type 5 (SPG5). Induced pluripotent stem cells (iPSCs) were generated by transfection with episomal plasmids carrying hOCT4, hSOX2, hKLF4, hL-MYC and hLIN28. The generated line iPS-SPG5-R486C was transgene-free, retained the specific mutation with no additional genomic aberrations, expressed pluripotency markers and was able to differentiate into cells of all germ layers in vitro. The generated iPS-SPG5-R486C line may be a useful resource for disease modelling of SPG5.
