Speech Assessment

Purpose The purpose of this tutorial was to describe the surgical management of palate-related abnormalities associated with 22q11.2 deletion syndrome. Craniofacial differences in 22q11.2 deletion syndrome may include overt or occult clefting of the palate and/or lip along with oropharyngeal variances that may lead to velopharyngeal dysfunction. This chapter will describe these circumstances, including incidence, diagnosis, and indications for surgical intervention. Speech assessment and imaging of the velopharyngeal system will be discussed as it relates to preoperative evaluation and surgical decision making. Important for patients with 22q11.2 deletion syndrome is appropriate preoperative screening to assess for internal carotid artery positioning, cervical spine abnormalities, and obstructive sleep apnea. Timing of surgery as well as different techniques, common complications, and outcomes will also be discussed. Conclusion Management of velopharyngeal dysfunction in patients with 22q11.2 deletion syndrome is challenging and requires thoughtful preoperative assessment and planning as well as a careful surgical technique.

Purpose This article reviews the psychosocial risks associated with 22q11.2 deletion syndrome, a relatively common genetic condition associated with a range of physical and psychiatric problems. Risks associated with developmental stages from infancy through adolescence and early adulthood are described, including developmental, learning, and intellectual disabilities as well as psychiatric disorders including anxiety, mood, and psychotic disorders. Other risks related to coping with health problems and related treatments are also detailed for both affected individuals and their families. Conclusion The article ends with strategies for addressing psychosocial risks including provision of condition-specific education, enhancement of social support, routine assessment of cognitive abilities, regular mental health screening, and referrals for empirically supported psychiatric and psychological treatments.

Aortic Arch Anomalies

16 second trimester fetuses with 22q11.2 deletion syndrome have been examined at anatomic-pathological investigation. Main cardiovascular diseases were ascending aorta hypoplasia with aortic valve stenosis (n = 6; 37.5%), truncus arteriosus (n = 5; 31.25%), tetralogy of Fallot (n = 3; 18.75%) and double-outlet right ventricle (n = 1; 6.25%). Ventricular septal defect was present in 16 cases. Associated aortic arch anomalies included interrupted aortic arch (n = 9; 56.25%), right aortic arch (n = 6; 37.5%), retroesophageal ring (n = 1; 6.25%) and aberrant right subclavian arteria (n = 5; 31.25%). 5 fetuses had left ventricular outflow tract obstructive lesions with interrupted aortic arch of type B combined with aberrant right subclavian arteria.

Congenital Cyanotic Heart Disease

Noninfectious cerebral aneurysms are rare in patients with congenital cyanotic heart disease. We present a patient with DiGeorge/velocardiofacial syndrome with a complex congenital cyanotic heart disease with a ruptured anterior communicating artery aneurysm. The 10-year-old child was managed by surgical clipping of the aneurysm. Surgical challenges included prominent veins in the Sylvian fissure, difficulty in differentiating arterial and venous bleed, and anesthetic risks. The patient recovered without any neurological deficits. This is the first report of a patient with 22q11.2 deletion syndrome, with a noninfectious cerebral aneurysm.

AbstractPurpose of ReviewThe 22q11.2 deletion syndrome (22q11DS) is associated with a broad spectrum of neurodevelopmental phenotypes and is the strongest known single genetic risk factor for schizophrenia. Compared to other rare structural pathogenic genetic variants, 22q11DS is relatively common and one of the most extensively studied. This review provides a state-of-the-art overview of current insights regarding associated neurodevelopmental phenotypes and potential implications for 22q11DS and beyond.Recent FindingsWe will first discuss recent findings with respect to neurodevelopmental phenotypic expression associated with 22q11DS, including psychotic disorders, intellectual functioning, autism spectrum disorders, as well as their interactions. Second, we will address considerations that are important in interpreting these data and propose potential implications for both the clinical care for and the empirical study of individuals with 22q11DS. Third, we will highlight variable penetrance and pleiotropy with respect to neurodevelopmental phenotypes in 22q11DS. We will discuss how these phenomena are consistently observed in the context of virtually all rare pathogenic variants and that they pose substantial challenges from both a clinical and a research perspective.SummaryWe outline how 22q11DS could be viewed as a genetic model for studying neurodevelopmental phenotypes. In addition, we propose that 22q11DS research can help elucidate mechanisms underlying variable expression and pleiotropy of neurodevelopmental phenotypes, insights that are likely relevant for 22q11DS and beyond, including for individuals with other rare pathogenic genetic variants and for individuals with idiopathic neurodevelopmental conditions.
