We report a 3.1-Mb de novo deletion of 3p21.31 in a 3.5-year-old female with cortical blindness, cleft lip, CNS abnormalities, and gross developmental delays. Examination of the region showed approximately 80 genes to be involved in the deletion. Functional analysis of the deleted genes suggests that several of them may be important in normal neuronal maturation and function. Thus, haploinsufficiency of one or more of these genes could potentially contribute to the observed phenotype. Our patient does not have clinical features that overlap completely with either proximal or distal 3p deletions, suggesting that the deletion seen in our patient leads to a distinct clinical phenotype not described previously.
