Type : Phenotype or locus, molecular basis unknown;
Description : In moyamoya disease, stenosis of the intracranial portion of the internal carotid
artery leads to secondary establishment of intracranial compensatory anastomoses at
different levels (leptomeninges, basal ganglia, and transdural) (summary by Sakurai
et al., 2004). For a general phenotypic description and a discussion of genetic heterogeneity
of moyamoya disease, see MYMY1 (252350).;
