Popis: The Stargardt’s Disease, Type 1 (STGD1) is associated with the loss of function mutations in ABCA4. This gene codes for a retina-specific, ATP-binding cassette (ABC) family transporter, involved in the transport of the key visual cycle intermediate, all-trans-retinaldehyde (atRAL), across the photoreceptor cell membranes. Here, we report the establishment of a patient-specific, iPSC line (LVPEIi008-A), that carries a homozygous nonsense mutation at (c.6088C > T) position, within exon 44 of ABCA4. The patient-specific skin fibroblasts were reprogrammed using episomal plasmids and the stably expanding iPSC line expressed the key stemness and pluripotency markers, maintained its chromosomal integrity and tested negative for mycoplasma.
