Generation of induced pluripotent stem cells from a young-onset Parkinson's disease patient carrying the compound heterozygous PLA2G6 p.D331Y/p.M358IfsX mutations

摘要

Mutations in PLA2G6 gene cause PLA2G6-associated neurodegeneration, including recessive familial type 14 of Parkinson's disease (PARK14). Previously, we identified PARK14 patients with compound heterozygous c.991G??T/c.1077G??A (p.D331Y/p.M358IfsX) mutations. The c.1077G??A mutation led to a four base-pairs deletion and frameshift mutation (p.M358IfsX) of PLA2G6 mRNA. We established induced pluripotent stem cells (iPSCs) from peripheral blood mononuclear cells of a female patient with compound heterozygous c.991G??T/c.1077G??A (p.D331Y/ p.M358IfsX) mutations by using Sendai-virus delivery system. The iPSCs exhibited pluripotency and in vivo differentiation potential. The iPSCs can be used for studying the molecular pathogenic mechanism of PARK14.
