ABSTRACT
Otocephaly ("agnathia") is a developmental field complex with structural defects limited to the craniofacial region. Previously, two infants with otocephaly, situs inversus totalis, renal defects, and vertebral and rib abnormalities were reported by Pauli et al. [Teratology 23:85-93, 1981]. We describe a similarly affected infant male, supporting the existence of this midline malformation association. A generalized disturbance in cell migration from the primitive streak may be its pathogenesis. A search for additional patients among cases of otocephaly may establish its prevalence, patterns of associated anomalies, and cause.

Congenital heart defects as a group represent a significant proportion of congenital malformations. Most are isolated and multifactorially determined; a relatively small proportion are due to a single gene defect, and result in an increased risk of recurrence among first-degree relatives. We have reported the cases of three male siblings with Ivemark's "asplenia" syndrome to support an autosomal recessive mode of inheritance. We have stressed the importance of early recognition of mendelian disorders with associated cardiac malformations to provide meaningful counseling regarding prognosis, medical management, and risk of recurrence.
