title: Central nervous system malformations and early end-stage renal disease in oro-facio-digital syndrome type I: a review.
abstract: Intracerebral cysts and porencephaly or arachnoid cysts are rarely but are repeatedly reported in orofaciodigital (OFD) syndrome type 1. We report on 2 families in which OFD syndrome type 1 was observed with central nervous system (CNS) malformations and 3 sporadic cases of OFD with CNS defects, most likely representing fresh mutations for OFD 1. In one case, vermis hypoplasia was present; in another, periventricular heterotopiae were noted. We review the literature on CNS anomalies in OFD syndromes and stress the difficulties in genetic counseling and functional prognosis for children of OFD 1 female carriers prenatally diagnosed with a malformation of the brain. As for CNS malformations, renal cystic disease is an often overlooked complication specific to OFD 1. In 1 family, cystic medullary disease was noted in OFD 1 carriers, leading 1 patient to dialysis by age 35 years and the other to severe renal insufficiency by age 28 years. Longitudinal follow-up of OFD 1 carriers should be performed, and renal function should be assessed in those with cysts because the functional prognosis of this developmental anomaly may be worse than usually reported in the literature.
