22q11.2 Deletion Syndrome: Are Motor Deficits More Than Expected For Iq Level?, Nancy Roizen, Anne Higgins, Kevin Antshel, Wanda Fremont, Robert Shprintzen, Wendy Kates

To examine motor function in children with 22q11.2 deletion syndrome (22q11.2) and a Full Scale IQ (FSIQ) comparable control group. This study was part of a prospective study of neuropsychological function in children 9 to 15 years of age with 22q11.2 and community control subjects and included children from these two populations with comparable FSIQs. Verbal IQs on the WISC-R for 40 children with 22q11.2 (88.4) and 24 community control subjects (87.2) were not different (P=.563). However, the performance IQs were (22q11.2; 81.1 vs community controls; 89.3; P

Objective: Velo-cardio-facial syndrome (VCFS; 22q11.2 deletion syndrome) represents one of the highest known risk factors for schizophrenia. Insofar as up to thirty percent of individuals with this genetic disorder develop schizophrenia, VCFS constitutes a unique, etiologically homogeneous model for understanding the pathogenesis of schizophrenia. Method: Using a longitudinal, case-control design, we acquired anatomic magnetic resonance images to investigate both cross-sectional and longitudinal alterations in surface cortical morphology in a cohort of adolescents with VCFS and age-matched typical controls. All participants were scanned at two time points. Results: Relative to controls, youth with VCFS exhibited alterations in inferior frontal, dorsal frontal, …

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 …

The majority of children with 22q11.2DS deletion syndrome (22q11.2DS) have learning disabilities, and a substantial number have mental retardation. Although cognitive data have been reported on several samples of children with 22q11.2DS, data on their early developmental milestones are limited. Methods: The present study used a retrospective design and asked parents to recall developmental milestones. The participants were 88 children with 22q11.2DS, 47 community controls, and 29 sibling controls. Results: Although very early gross motor and expressive language milestones did not differ significantly from comparison groups, subsequent gross motor and expressive language milestones did, suggesting that children with 22q11.2DS may …

Background: Up to 30% of young adults with velocardiofacial syndrome (VCFS; 22q11.2 deletion syndrome) develop schizophrenia or psychosis. Identifying the neuroanatomic trajectories that increase risk for psychosis in youth with this genetic disorder is of great interest. Methods: We acquired high-resolution anatomic MR images and measures of psychiatric function on 72 youth with VCFS, 26 unaffected siblings and 24 age-matched community controls at two timepoints, between late childhood (mean age, 11.9 years) and mid-adolescence (mean age, 15.1 years). Results: With the exception of cranial gray matter and orbitofrontal prefrontal cortex, neuroanatomic trajectories in youth with VCFS were comparable to unaffected …

Velo-cardio-facial syndrome/DiGeorge syndrome, also known as 22q11.2 deletion syndrome (22q11DS) is the most common microdeletion syndrome, with an estimated incidence of 1/2,000 – 1/4,000 live births. Approximately 9–11% of patients with this disorder have an overt cleft palate (CP), but the genetic factors responsible for CP in the 22q11DS subset are unknown. The TBX1 gene, a member of the T-box transcription factor gene family, lies within the 22q11.2 region that is hemizygous in patients with 22q11DS. Inactivation of one allele of Tbx1 in the mouse does not result in CP, but inactivation of both alleles does. Based on these data, …

At least three research groups have reported that autism is diagnosed in up to 20% of children with velocardiofacial syndrome (VCFS). However the degree of phenotypic overlap between VCFS-affected children with autism and those with idiopathic autism has not been established. The purpose of this study was to define and differentiate the behavioral phenotype of autism in samples of children with either (VCFS) or idiopathic autism. Five groups of children ages 5–15 were included in the between-group design. Parent report of autism behaviors (based on the Autism Diagnostic Interview-Revised, ADI-R) were compared between children with VCFS, children with VCFS and …
