    Moyamoya disease (MMD) is a rare cerebral vasculopathy characterized by bilateral internal carotid artery stenosis and often leads to stroke in children or young adults. Although familial inheritance is well recognized, the genetic basis of MMD remains poorly understood. A 2-stage genome-wide association study was conducted involving 1492 cases and 5084 controls. In the discovery stage, logistic regression was used to test associations, and imputation was conducted based on genotyped single-nucleotide polymorphisms (SNPs). In the validation stage, the top significant SNPs were again genotyped in an independent cohort. Fixed-effects inverse variance-weighted meta-analysis was used in the combined discovery and validation samples. Furthermore, association analysis was conducted in subgroups

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Discuss with your doctor

  • moyamoya disease genetic counseling High

    RNF213 variant increases moyamoya disease risk; genetic counseling clarifies inheritance and identifies at-risk family members

    Refer to genetic counselor and/or neurologist specializing in cerebrovascular disease

Screening

  • moyamoya disease neurovascular imaging High

    RNF213 variant carries strong genetic risk for moyamoya disease (OR=1.786); early detection of cerebrovascular changes enables preventive management

    Baseline MRI/MRA or CTA to screen for moyamoya disease features, especially if experiencing neurological symptoms
