ResumoWe report on a child with apparent Sotos syndrome (cerebral gigantism) and partial duplication of the short arm of chromosome 20 mosaicism. Trisomy 20p11.2-p12.1 was diagnosed using cytogenetic and FISH studies. The somatostatin receptor 4 (SSTR4) gene is included in the duplicated segment. This suggests that a dosage effect of this gene might be related to some of the clinical findings observed in our patient. The present observation emphasizes the importance of chromosome analysis in patients with well-delineated but sporadic conditions.
