Generation and characterization of the CSSi021-A (15665) human induced pluripotent stem cell line from a Smith-Magenis syndrome patient with a heterozygous RAI1 mutation.

Smith-Magenis syndrome (SMS) is a rare neurodevelopmental disorder caused by haploinsufficiency of the Retinoic Acid Induced 1 (RAI1) gene located at 17p11.2. It is estimated that approximately 90% of patients have a 17p11.2 deletion, including the RAI1 gene, while the remaining 10% exhibit a heterozygous mutation in the RAI1 gene. In this study, we report the generation of a human induced pluripotent stem cell (hiPSC) line derived from a 14-year-old female with an RAI1 mutation, which led to the onset of the SMS phenotype, starting from primary fibroblasts.
