Abstract
OBJECTIVE
The prevalence of moyamoya disease (MMD) is relatively high in East Asia, whereas the susceptibility genes of MMD have not been identified.
METHODS
Here, we reported 3 patients diagnosed with MMD from 1 single family, including a 53-year-old mother (case 1) and her 32-year-old and 29-year-old daughters (cases 2 and 3). The younger daughter was diagnosed with cerebral hemorrhage. Computed tomographic angiogram showed the typical signs of MMD in 3 patients.
RESULTS
Clinical whole-exome sequencing was performed in 3 daughters of case 1, and RASA1 mutations in chr5: 87,376,389 and NM_002890.2: c.2012-4C > T were determined to have the strongest correlation with MMD. RASA1 mutations were verified in case 1, husband of case 1 and the descendant of case 3 by using Sanger sequencing.
CONCLUSIONS
According to the findings of literature review, this is the first study indicating the association between RASA1 mutations and MMD.
