Abstract:
Sotos syndrome is one of the overgrowth syndromes, and can present with intellectual disability, behavioral problems and tall stature. In some cases, seizures, pectus deformity, cardiac and renal anomalies may be identified. Here we report two Indian children with Sotos syndrome whose initial presentation was macrocephaly and behavioral problems, respectively. The pathogenic variants in NSD1 gene were confirmed by next generation sequencing. The gene variants in the two children, one male and one female; were NSD1: c.2362C>T and NSD1: c.5474dup, respectively, leading to premature termination of protein formation.
