Cooper-Wang-Jabs syndrome is a multiple malformation syndrome characterized by atresia of the auditory canal together with ventricular septal defect, anteriorly displaced anus, mild clubfoot, and intellectual deficit. It has been described only once, in two sisters. The mode of inheritance is most likely autosomal recessive.
Features include very common findings: Brachycephaly, Malar flattening, Posteriorly rotated ears, and Abnormality of the middle ear and others; and common findings: Strabismus, Abnormal rib morphology, Congenital diaphragmatic hernia, and Missing ribs and others.
