Generation of 3 clones of induced pluripotent stem cells (iPSCs) from a patient affected by Autosomal Recessive Osteopetrosis due to mutations in TCIRG1 gene

Abstract

Autosomal recessive osteopetrosis (ARO) is a rare inherited disorder leading to increased bone density with impairment in bone resorption. Among the genes responsible for ARO, the TCIRG1 gene, coding for the a3 subunit of the osteoclast proton pump, is mutated in more than 50% of the cases, increasing the importance of TCIRG1-iPSCs as disease model. We generated 3 iPSC clones derived from Peripheral Blood Mononuclear Cells (PBMCs) of a patient carrying the heterozygous mutations p.Y512X and c.2236 + 1G > A. A Sendai virus-based vector was used and the iPSCs were characterized for genetic identity to parental cells, genomic integrity, pluripotency, and differentiation ability.
