We report two sibs of Turkish descent with multiple congenital
anomalies including severe microcephaly, hygroma colli, cystic renal
dysplasia, and bilateral cutaneous syndactyly of toes IV-V. In
addition, the second sib presented with bilateral fusion of the
eyelids, a bicornuate uterus, and clitoromegaly. The parents are first
cousins, which suggests autosomal recessive inheritance. In reviewing
previously published reports, several cases were found with cerebral,
renal, and digital anomalies as the main features. Several of the
additional symptoms present in the second sib were suggestive of Fraser
syndrome, but the severe microcephaly in both sibs is unusual. The
differential diagnosis is discussed, including the possibility of an
entirely new entity in the broad spectrum of syndromes with cerebral,
renal, and digital anomalies.
