Generation of integration free induced pluripotent stem cells from fibrodysplasia ossificans progressiva (FOP) patients from urine samples

Fibrodysplasia ossificans progressiva (FOP) is an extremely rare, autosomal dominant transmitted genetic disease. Patients experience progressive bone formation replacing tendons, ligaments, muscle and soft tissue. Cause of FOP are gain-of-function mutations in the Bone Morphogenetic Protein (BMP) receptor Activin A receptor type 1 (ACVR1) (Kaplan et al., 2008). The most common mutation is R206H, which leads to the substitution of codon 206 from arginine to histidine (Shore et al., 2006).
