Additionally, recurrent heterozygous mutations of ACVR1 were associated with diseases in human such as fibro dysplasia ossificans progress (FOP) [53], diffuse intrinsic pontine gliomas (DIPGs) [54] and pediatric midline high-grade astrocytoma (mHGAs) [55]. The gene discussed is ACVR1; the disease is fibrodysplasia ossificans progressiva.
