Deleción proximal de 6q superpuesta con fenotipo facial de Toriello-Carey: hallazgos prenatales, evolución clínica, diagnóstico diferencial y revisión. Sindromología molecular , 9 (1), 15–21. https://doi.org/10.1159/000484427https://doi.org/10.1159/000484427http://hdl.handle.net/11447/5664Proximal deletion of 6q is a relatively rare chromosomal abnormality. Reported patients have deletions of different sizes but share partial overlap and present with similar clinical features, and some of them were described prior to the introduction of chromosome microarrays. We describe a male patient with prenatal sonographic findings of nuchal edema, intrauterine growth restriction, renal pelvis dilatation, and oligohydramnios. At birth, facial dysmorphism, retro/micrognathia, a short and wide neck as well as cardiovascular and renal anomalies were noted. His clinical evolution has been marked by failure to thrive, severe developmental delay, and cognitive impairment. The diagnosis of Toriello-Carey syndrome (TCS) was based on his “gestalt.” aCGH identified a de novo proximal deletion of 17 Mb in 6q (6q12q14.3). Deletion 6q13q14 seems to be responsible for the main facial features and should be considered within the differential diagnosis of TCS.enDeleción de 6qDismorfismo facialSíndrome de Toriello-CareyArticle
