先天性颅神经异常支配性疾病及分子遗传学研究进展

先天性颅神经异常支配性疾病（congenital cranial dysinnervation disorders,CCDDs）为先天性、非进行性散发或家族性的颅神经肌肉疾病,其病因为一条或多条颅神经发育异常或完全缺如,从而引起原发或继发的对肌肉的异常支配。可表现为垂直眼球运动异常,水平眼球运动异常和面肌麻痹。以往这类疾病常被称为先天性纤维化综合征,最近的神经病理学、神经影像学和分子遗传学研究表明该类疾病是由于脑干颅神经核和（或）颅神经的发育异常引起。本文对不同类型CCDDs的临床及分子遗传学研究进展作一综述。

Advances in clinical and molecular genetics of congenital cranial dysinnervation disorders

Congenital cranial dysinnervation disorders (CCDDs) are congenital non-progressive, sporadic or familial abnormalities of cranial musculature that result from developmental abnormalities of, or the complete absence of, one or more cranial nerves with primary or secondary muscle dysinnervation. These disorders include vertical disorders of ocular motility, horizontal disorders of ocular motility and disorders with abnormalities of facial motility that were previously referred to as "congenital fibrosis syndromes". The advances in clinical and molecular genetics of congenital cranial dysinnervation disorders are reviewed.
