Abstract:
Fourteen children (of Arab ethnic origin) with Sotos syndrome are described. They were referred to King Khalid University Hospital, Riyadh between July 1992 and June 1997. Their phenotypic characteristics were compared with established diagnostic criteria. There was a male:female ratio of 1.3:1 and a high rate of consanguinity (36%) among parents. At birth, 54% were large and about one-third showed increased height and occipitofrontal head circumference (OFHC). The neonatal histories revealed respiratory and feeding problems in 21%, followed later by delayed motor milestones and speech development in 57%. During childhood, weight, height and OFHC increased further to 97th centile in 71%, 71% and 93%, respectively. A seizure disorder affected 43%, and 75% had mental retardation (IQ 70). A non-specific EEG abnormality was found in half of those with seizures. Cranial CT/MRI showed ventricular dilatation in 15% and one patient had corpus callosum dysgenesis. Abdominal ultrasound revealed hydronephrosis in two patients. Radiological cephalometric measurements showed relative prognathism in cases of Sotos syndrome compared with controls (p =0.003). The study highlights the importance of considering Sotos syndrome in children who present with psychomotor delay.Language: English
