7q11.23 duplication syndrome is a disease caused by duplication of a region of chromosome 7 comprising 26 genes. The first case described in the literature was reported by Somerville et al. in 2005, who described a patient with dolichocephaly, high and narrow forehead, long eyelashes, high and wide nose, short philtrum, high arched palate, dental malocclusion, retrognathia, and severe language delay. We report the case of a Colombian patient with 7q11.23 duplication by comparative genomic hybridization techniques, and classical clinical findings, this being the first reported case in Colombia and Latin America.
