Sotos syndrome is an overgrowth syndrome with characteristic facial dysmorphism, variable severity of learning disabilities and macrocephaly with overgrowth. Haploinsufficiency of the nuclear receptor SET domain-containing protein 1 (NSD1) gene located on 5q35 has been implicated as the cause of Sotos syndrome. This study was performed to investigate the mutation spectrum of NSD1 abnormalities and meaningful genotype-phenotype correlations in Korean patients with Sotos syndrome.

In particular, coronal synostosis evidences a higher tendency to be genetically caused, and TWIST1 and FGFR3 have been identified as major causative genes. The authors analyzed the clinical and molecular characteristics of Korean patients with coronal synostosis in this study.

OCA1, the most common and severe form, is caused by mutations in the tyrosinase (TYR) gene. OCA4, caused by mutations in the SLC45A2 gene, has frequently been reported in the Japanese population.
