Velo-cardio-facial syndrome (VCFS) is a genetic disorder caused by a microdeletion of chromosome 22q11.2. Although there is some variability, VCFS is associated with a characteristic physical, behavioral, and cognitive phenotype. This review article focuses on aspects of language and literacy development in VCFS, describing what is known and offering avenues for future research. The most consistently reported language and literacy findings in the VCFS population include reading, spelling, phonological processing, and auditory verbal rote memory abilities as areas of relative strength. Receptive language abilities are noted to be relatively stronger than expressive language abilities in individuals with VCFS. Speech disorders …

Background: Velo-cardio-facial syndrome (VCFS, MIM#192430, 22q11.2 Deletion Syndrome) is a genetic disorder caused by a deletion of about 40 genes at the q11.2 band of one copy of chromosome 22. Individuals with VCFS present with deficits in cognition and social functioning, high risk of psychiatric disorders, volumetric reductions in gray and white matter (WM) and some alterations of the WM microstructure. The goal of the current study was to characterize the WM microstructural differences in individuals with VCFS and unaffected siblings, and the correlation of WM microstructure with neuropsychological performance. We hypothesized that individuals with VCFS would have decreased indices …

Objective: Velo-cardio-facial syndrome (VCFS) is caused by a microdeletion of approximately 40 genes from one copy of chromosome 22. Expression of the syndrome is a variable combination of over 190 phenotypic characteristics. As of yet, little is known about how these phenotypes correlate with one another or whether there are predictable patterns of expression. Two of the most common phenotypic categories, congenital heart disease and cleft palate, have been proposed to have a common genetic relationship to the deleted T-box 1 gene (TBX1). The purpose of this study is to determine if congenital heart disease and cleft palate are correlated …

Velo-cardio-facial syndrome (VCFS) is the most common microdeletion syndrome in humans and is probably the most frequent genetic cause of psychosis currently known. Many psychiatric disorders have been reported to occur in people with VCFS including, but not limited to schizophrenia, unipolar and bipolar mood disorders (with or without psychotic features), schizoaffective disorder, psychosis NOS, social phobia, generalized and separation anxiety, obsessive-compulsive disorder, autism spectrum disorder, cognitive impairment, and ADHD. This report describes the psychiatric onset and development of catatonia in an adolescent female with VCFS that was undiagnosed until 15 years of age. Catatonia may be a relatively common …

Introduction: Velo-cardio-facial syndrome (VCFS) has been identified as an important risk factor for psychoses, with up to 32% of individuals with VCFS developing a psychotic illness. Individuals with VCFS thus form a unique group to identify and explore early symptoms and biological correlates of psychosis. In this study, we examined if cortical gyrification pattern, i.e. gyrification index (GI) can be a potential neurobiological marker for psychosis. Method: GIs of 91 individuals with VCFS were compared with 29 siblings and 54 controls. Further, 58 participants with VCFS, 21 siblings and 18 normal controls were followed up after 3 years and longitudinal …
