Pitt-Rogers-Danks syndrome (PRDS) is a rare, presumed autosomal recessive, syndrome with pre- and postnatal growth retardation, microcephaly, characteristic facial appearance, seizures, unusual palmar creases and developmental delay. Since the first description in 1984, only 7 cases have been reported. We report the identification of a 4p microdeletion in 2 new patients, who were previously diagnosed with PRDS, as well as the sibs in Pitt et al. [1984]. PRDS can no longer be considered autosomal recessive. Although our cases are attributable to a microdeletion in 4p16, it is uncertain if the critical region involves a single locus or multiple loci or to what extent this region overlaps with the critical region for Wolf-Hirschhorn syndrome. |
