Fibroblasts from a male patient with compound heterozygous variants in the tyrosine hydroxylase gene (TH; OMIM: 191290; c.[385-C>T]; [692-G>C]/p.[R129*]; [R231P]), the rate-limiting enzyme for dopamine synthesis, were reprogrammed to iPSCs using episomal reprogramming delivering the reprogramming factors Oct3/4, Sox2, L-Myc, Lin28, Klf4 and p53 shRNA Okita et al. (2011). Pluripotency of TH-1 iPSC was verified by immunohistochemistry and RT-PCR analysis. Cells exhibited a normal karyotype and differentiated spontaneously into the 3 germ layers in vitro. TH-1 iPSC represents the first model system to study the pathomechanism of this rare metabolic disease and provides a useful tool for drug testing.
