The neurocognitive phenotype in velo-cardio-facial syndrome: a developmental perspective

Abstract

Although research has focused primarily on the wide range of variability in the cognitive phenotype between individuals with velo-cardio-facial syndrome (VCFS), we know relatively little about the extent to which within-individual expressions of the cognitive phenotype remain stable throughout development. General cognitive functioning in the low borderline range is the most consistent cognitive finding. Stronger reading decoding and spelling skills as well as auditory/verbal rote memory skills have been reported to be areas of relative strength. Conversely, significant visuospatial dysfunction, diminished math attainment, and executive dysfunction have all been reported as phenotypic. We propose several considerations that could advance our knowledge of developmental changes in the VCFS cognitive phenotype. The most salient of these is the need for more longitudinal designs with carefully matched control participants.
