A rare chromosomal anomaly syndrome resulting from the partial deletion of the long arm of chromosome 17. The disease is characterised by renal cystic disease, maturity onset diabetes of the young type 5 and neurodevelopmental disorders, such as cognitive impairment, developmental delay (particularly of speech), autistic traits and autism spectrum disorder. Mullerian aplasia in females, macrocephaly, mild facial dysmorphism (high forehead, deep set eyes and chubby cheeks) and transient hypercalcaemia has also been reported. [from
