Generation of an ITPR1+/- and isogenic control induced pluripotent stem cell line for SCA15/16 model development.

Spinocerebellar ataxia type 15/16 (SCA15/16) is a rare neurodegenerative disorder caused by heterozygous deletions of ITPR1, leading to haploinsufficiency of the encoded endoplasmic reticulum membrane calcium channel. Patients present with progressive gait disturbances, abnormal eye movements, difficulties with speech and swallowing, and tremors associated with atrophy of the cerebellum. Using CRISPR/Cas9 technology, we generated ITPR1+/- and isogenic control induced pluripotent stem cell (iPSC) lines from PGP1 iPSCs for SCA15/16 model development. The clones were genotyped, karyotyped, and assessed for pluripotency and differentiation potential.
