| A recently described syndrome with characteristics of a variable phenotype involving moderate to severe intellectual deficit, significant speech delay, persistent feeding difficulties, growth retardation and dysmorphic features. It has been described in fewer than 25 patients to date. Facial features include downslanting palpebral fissures, low-set ears and prominent nasal bridge. Most patients also have a high-arched palate or cleft palate. Some individuals have an ectodermal dysplasia-like phenotype, with thin, transparent skin and abnormalities of the hair and teeth. The size of the deletions is variable from 35 kb to 10.4 Mb. Haploinsufficiency of SATB2 is responsible for several of the clinical features. |
