Relation between oculo-auriculo-vertebral (OAV) dysplasia and three other non-random associations of malformations (VATER, CHARGE, and OEIS).
Using a statistical methodology, we aimed to identify a group of probable cases of oculo-auriculo-vertebral (OAV) dysplasia and to investigate possible relationships between different patterns of congenital malformations. Among 5,260 infants with multiple malformations collected from 4 large registers of congenital malformations, we identified 312 probable OAV cases. With the same technique, we ha
