WARS2相关复合氧化磷酸化缺陷
WARS2-related combined oxidative phosphorylation defect
定义 英文原文(暂无中文)
A rare mitochondrial oxidative phosphorylation disorder characterized by a spectrum of three main clinical phenotypes comprising a severe neonatal phenotype with early fatal lactic acidosis, a more protracted course with early-onset developmental delay, motor weakness, extrapyramidal signs, and with or without epilepsy, and a phenotype with normal early development and Parkinson-like symptoms starting around the age of one year. Additional, variably reported, signs and symptoms include cardiomyopathy, optic anomalies, hepatosplenomegaly, and abnormal brain MRI findings, among others. Deficiencies in mitochondrial oxidative phosphorylation enzymes are inconsistent.
