Trisomy 18 syndrome (T18) is a clinical and genetic disorder, which has a full extra chromosome 18 in each cell, variant that is called free trisomy. In addition, it can occur in partial and mosaic form. It is characterized by intrauterine growth restriction, psychomotor and mental retardation, characteristic craniofacial findings, congenital heart disease, hypoplastic pelvis, clenched hand and rocker-bottom foot, among others. The mosaic T18 occurs when cells with T18 and normal cell lines exist in the same individual and correspond to 5% of cases. Trisomía 18 en mosaico. Serie de casos Mosaic trisomy 18.
