White-Sutton syndrome is a rare type of autosomal dominant neurodevelopmental disorder caused by mutations, mostly de novo, in the POGZ gene. No more than 120 patients have been described so far in the literature. Common clinical manifestations include intellectual disability, developmental delay, autism spectrum disorder, other behavioral abnormalities, sleeping problems, hyperactivity and visual problems. We describe a 20-year-old male patient from Colombia who presented with delayed psychomotor development, intellectual disability, obesity, sleep difficulties, hypotonia, hypogonadism, gynecomastia, visual abnormalities and several facial dysmorphisms. Genetic testing showed a novel heterozygous frameshift variant (c.3308del; p.Leu1103Profs*19) in the POGZ gene (NM_015100.3). This is the first report of a diagnosed patient with WHSUS in Colombia.
