Moyamoya disease with early-onset achalasia

Synonyms
MOYAMOYA 6 WITH ACHALASIA; Moyamoya disease 6 with achalasia
Modes of inheritance
Autosomal recessive inheritance (Orphanet)

Summary

Moyamoya disease-6 is a progressive vasculopathy characterized by occlusion of the terminal portion of the internal carotid arteries and its branches, and the formation of compensatory neovascularization and the moyamoya, or 'puff of smoke,' appearance of these vessels on angiogram. Affected individuals may present with ischemic strokes, intracerebral hemorrhage, or transient ischemic attacks. Patients with MYMY6 usually present early in life with achalasia. Hypertension and Raynaud phenomenon may be associated features (summary by Wallace et al., 2016; Herve et al., 2014). For a general phenotypic description and a discussion of genetic heterogeneity of moyamoya disease, see MYMY1 (252350). [from OMIM]
