定义 英文原文(暂无中文)

A rare disorder of pentose phosphate metabolism characterized by developmental delay and intellectual disability, delayed or absent speech, short stature, and congenital heart defects (such as ventricular septal defect, atrial septal defect, and patent foramen ovale). Additional reported features include hypotonia, hyperactivity, stereotypic behavior, ophthalmologic abnormalities (bilateral cataract, uveitis, strabismus), hearing impairment, and variable facial dysmorphism, among others.
