ABSTRACT
El síndrome otopalatodigital tipo 2 (OPD2), es una rara entidad con herencia recesiva ligada al cromosoma X, letal, caracterizada por facies anormales con hipoplasia centrofacial, hipertelorismo ocular, paladar hendido, talla baja, huesos largos curvos, sindactilia en pies y manos y anomalías óseas. Usualmente originadas en mutaciones en el gen de la filamina A (FLNA). Se reporta un caso, con diagnóstico prenatal de osteocondrodisplasia que posteriormente por hallazgos al examen físico y radiológicos del recién nacido se clasifico como síndrome otopalatodigital tipo 2.Otopalatodigital syndrome, type 2 (OPD2), is a rare entity with recessive heredity linked to the X chromosome, lethal, characterized by abnormal facies, with centro-facial hypoplasia, ocular hypertelorism, cleft palate, low height, curved long bones, syndactyly, and osseous anomalies on feet and hands.
