Abstract
BACKGROUND
Moyamoya syndrome represents an etiologically heterogeneous cerebral evolutive angiopathy. It can be associated with both well-characterized and recently described genetic conditions with mendelian inheritance.
CASE REPORT
We report the case of a moyamoya angiopathy in a prematurely born girl affected by congenital heart defect, mild facial dysmorphism, mild neurodevelopmental delay and borderline cognitive profile, associated to a de novo complex rearrangement involving the terminal segment of the short arm of chromosome 6.
CONCLUSION
To the best of our knowledge, this is the second case described of pediatric moyamoya syndrome associated with a 6p complex rearrangement. Adding this case to the pertinent literature, we discuss the pathogenic role of rearrangements in 6p region in moyamoya syndrome and suggest to investigate in this region potential genes involved in angiogenesis or vascular homeostasis.
