Grange Syndrome
Grange syndrome is characterised by stenosis or occlusion of multiple arteries (including the renal, cerebral and abdominal vessels), hypertension, brachysyndactyly, syndactyly, increased bone fragility, and learning difficulties or borderline intellectual deficit. Congenital heart defects were also reported in some cases.
Epidemiology
So far, the syndrome has been reported in six patients from three families.
Genetic counseling
The mode of transmission remains unclear, both autosomal recessive and autosomal dominant inheritance with decreased penetrance and parental gonadal mosaicism have been proposed.
