22q11 Deletion Syndrome with Vascular Anomalies
DiGeorge syndrome, also termed 22q11.2 deletion syndrome, represents a spectrum of disorders that include thymic aplasia/hypoplasia, parathyroid aplasia/hypoplasia, conotruncal vascular anomalies, and velocardiofacial (Shprintzen) syndrome. This case report describes a novel constellation of cardiovascular anomalies in a 31-year-old patient with 22q11.2 deletion confirmed by fluorescence in sit...
متن کامل22q11 deletion syndrome: current perspective
Chromosome 22q11 is characterized by the presence of chromosome-specific low-copy repeats or segmental duplications. This region of the chromosome is very unstable and susceptible to mutations. The misalignment of low-copy repeats during nonallelic homologous recombination leads to the deletion of the 22q11.2 region, which results in 22q11 deletion syndrome (22q11DS). The 22q11.2 deletion is as...
متن کاملHypoparathyroidism and 22q11 deletion syndrome.
AIMS To investigate a population of individuals with 22q11 deletion syndrome for hypocalcaemia. METHODS A detailed clinical history enquiring into symptoms of hypocalcaemia and blood sampling to assess for hypocalcaemia and hypoparathyroidism, of patients outside the neonatal period known to have the 22q11 microdeletion from fluorescent in situ hybridisation studies was taken. RESULTS Sixty...
متن کاملGENES AND SCHIZOPHRENIA Molecular Mechanisms in 22q11 Deletion Syndrome
It is now well recognized that as well as having a characteristic facial dysmorphology and a range of congenital abnormalities, individuals with chromosome 22q11 deletion syndrome (22q11DS) have a greatly increased risk of developing psychosis, in particular schizophrenia. The majority of deletions span a large 3Mb region at 22q11. However, the presence of affected individuals carrying smaller ...
متن کاملGrowth charts for 22q11 deletion syndrome.
The purpose of this work was to create growth curves specific to the 22q11.2 deletion syndrome. Growth parameters on 188 patients (86 females, 102 males) followed by a group of three dysmorphologists were collected by retrospective chart review. Growth charts for body mass, length/height, and head circumference were generated using a semi-parametric model with goodness-of-fit tests. The resulti...
