Orthopaedic manifestations and treatment outcome of two siblings with Escobar syndrome and homozygous mutations in the CHRNG gene.

Escobar syndrome is a nonlethal subtype of multiple pterygium syndromes, characterized by webbing across the joints, congenital joint contracture, facial dysmorphism and a variety of other congenital anomalies. We report orthopaedic manifestation and the treatment outcome of two siblings with Escobar syndrome caused by homozygous mutations of the CHRNG gene.
