No overt abnormality, but children too young to provide an adequate speech sample or poor cooperationįeeding.
About 26.6% of persons have no palatal involvement. It is important to note that the reported incidence of palatal abnormalities varies widely, depending on numerous factors including the reporting technique, the diligence with which the diagnosis is sought, the age at which the individual is evaluated, and the inherent ascertainment bias of any single center. Often children initially diagnosed with 22q11.2DS because of a cardiac defect are subsequently found to have unrecognized but clinically significant VPI. Submucosal cleft palate and/or a bifid uvula are also fairly prevalent, whereas overt cleft palate and cleft lip/palate are less frequently observed. The most common abnormality, velopharyngeal incompetence (VPI), may be a structural problem (short palate), a functional problem (hypotonia of the velopharyngeal musculature), or a combination of the two. In a review of 1,048 individuals with 22q11.2DS, 67% of individuals had a palatal abnormality ( Table 3) – a finding consistent with previous studies. Includes right aortic arch, vascular ring, double aortic arch, and left aortic arch with aberrant right subclavian artery Note: The 22q11.2 recurrent deletion cannot be identified by routine analysis of G-banded chromosomes or other conventional cytogenetic banding techniques. Genomic testing methods that determine the copy number of sequences can include chromosomal microarray (CMA) or targeted deletion analysis. (3) Although pathogenic variants in a single gene in the 22q11.2 region are not causative of 22q11.2DS, several genes of interest have been identified (see Differential Diagnosis and Molecular Genetics). (2) The phenotype of significantly larger or smaller deletions within this region may be clinically distinct from 22q11.2DS (see Genetically Related Disorders). Note: (1) Since these deletions are recurrent and mediated by segmental duplications, the unique genetic sequence that is deleted is the same in all individuals with each deletion however, the reported size of the deletion may: (a) may be larger if adjacent segmental duplications are included in the size and (b) may vary based on the design of the microarray used to detect it (see Molecular Pathogenesis). Carbonated drinks and alcohol consumption may exacerbate hypocalcemia.

Surveillance: Evaluation for nasal speech quality after language emergence antibody studies to assess seroconversion reevaluate immune status in childhood before administration of live vaccines annual complete blood count and differential serum ionized calcium every three to six months in infancy, every five years through childhood, every one to two years thereafter, preoperatively and postoperatively, and regularly during pregnancy TSH and free T4 annually ophthalmologic evaluation between age one and three years or as indicated audiology evaluation in infancy, at preschool age, and in school age children developmental assessments annually annual clinical surveillance for scoliosis dental examination every six months.Īgents/circumstances to avoid: Infants with lymphocyte abnormalities should not be immunized with live vaccines (e.g., oral polio, MMR). Treatment of manifestations: Cardiac anomalies are treated as recommended by cardiologist surgical repair for palate anomalies as recommended by otolaryngologist feeding issues are treated with modification of spoon placement standard treatment for gastroesophageal reflux and gastrointestinal dysmotility immune deficiency requires aggressive treatment of infections rarely, prophylactic antibiotics, IVIG therapy, or thymic transplantation are required irradiated blood products are recommended until normalization of the immune system can be confirmed treatment of autoimmune disease as per immunologist calcium supplementation and referral to an endocrinologist and nephrologist because of increased risk of renal calculi if long-term supplementation is required standard treatment for growth hormone deficiency standard treatment for ocular anomalies hearing aids may be helpful for hearing loss occupational, physical, and speech therapy with introduction of sign language by age one year, educational and behavioral therapy support and treatment for psychiatric disease as indicated activity restriction as recommended by an orthopedist for cervical spine anomalies surgery and treatment as recommended by a nephrologist for renal anomalies routine dental treatment with consideration of sealants.
