- An iPSC line derived from a patient with GTPCH deficiency has been generated.
- The cells show all hallmarks of pluripotency.
- They represent the first iPSC model system to study this rare metabolic disease.
Fibroblasts from a female patient carrying a heterozygous variation in GTP cyclohydrolase 1 (GCH1; OMIM: 600225; HGNC: 4193; c.235_240del/p.(L79_S80del)), the rate-limiting enzyme of tetrahydrobiopterin (BH4) synthesis, were reprogrammed to iPSCs using the Cytotune®-iPS 2.0 Sendai Reprogramming Kit (Invitrogen) delivering the four reprogramming factors Oct3/4, Sox2, c-Myc and Klf4. Pluripotency of HDMC0061i-GCH1 was verified using immunohistochemistry and RT-PCR analysis. Cells differentiated spontaneously into the 3 germ layers in vitro and presented a normal karyotype. HDMC0061i-GCH1 represents the first model system to elucidate the pathomechanism underlying this rare metabolic disease and a useful tool for drug testing.
