| A recently described syndrome with characteristics of developmental delay and facial dysmorphism. Facial features include flat facies, downslanting palpebral fissures, low-set and malformed ears. Orofacial clefting, heart defects, short stature, feeding difficulties and hypotonia can be observed. This syndrome is caused by an interstitial deletion encompassing 16p11.2-p12.2. These deletions arise de novo and are flanked by segmental duplications suggesting that the underlying mechanism is non-allelic homologous recombination. |
