-
A rare chromosomal anomaly syndrome resulting from the partial trisomy of the long arm of chromosome 9. The disease has a highly variable phenotype principally characterised by developmental delay, short stature, intellectual disability and craniofacial dysmorphism (microcephaly, broad forehead, low set ears, epicanthus, prominent nose and retrognathia). Cardiac, ocular, thyroid and oesophagus defects along with central nervous system and behavioural/psychiatric abnormalities have also been reported.
