In cerebral palsy (CP) muscles are often shortened so much that they restrict joint range of motion and the muscles themselves are weak. Thus, ‘shortness’ and ‘weakness’ are two important needs that clinicians must address.
Cohort-based whole exome and whole genome sequencing and copy number variant (CNV) studies have identified genetic etiologies for a sizable proportion of patients with cerebral palsy (CP). These findings indicate that genetic mutations collectively comprise an important cause of CP.
