RESUMENEl síndrome de duplicación 7q11.23 es una patología causada por la duplicación de una región del cromosoma 7 que comprende 26 genes. El primer caso descrito en la literatura fue reportado por Somerville et al., en el año 2005, quienes describieron un paciente con dolicocefalia, frente alta y estrecha, pestañas largas, nariz alta y ancha, filtrum corto, paladar ojival, maloclusión dental, retrognatia y retardo grave en el lenguaje. Presentamos una paciente colombiana con hallazgo de duplicación 7q11.23 mediante técnicas de hibridación genómica comparativa y hallazgos clínicos clásicos. Este es el primer caso comunicado en Colombia y en América Latina. ABSTRACT 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
