Clinical Genetics, Synlab MVZ Humangenetik Freiburg RCV004801494 SCV005421122 likely pathogenic Chromosome 22q11.2 deletion syndrome, distal 2023-07-25 no assertion criteria provided clinical testing Distal deletions of the chromosomal region 22q11.2 D-E/F are described for a milder phenotype than the typical Di-George syndrome spectrum. Mikhail et al., 2014 described 9 unrelated patients with distal 22q11.2 deletions that show variable neurodevelopmental phenotypes, including psychiatric manifestations. Penetrance is reduced and the the phenotype variable (McDonald-McGinn et al., GeneReviews, 2020). Oliveira et al. (2019) reviewed the literature for cases of 22q11.2 D-E deletions. A total of 33 individuals were reported across 15 studies, with the common phenotypic findings including congenital heart disease (truncus arteriosus was the most common), prematurity and low birth weight, language development delay, bone malformations, facial dysmorphisms, and a wide range of intellectual disability. We rate the 669 kb deletion on 22q11q2 as Likely pathogenic.
