0 Comment
New research study ongoing directed by Dr. Thomas Liehr of the Jena Institute of Human Genetics in Jena, Germany to learn if diagnosing Cat-Eye syndrome via visual diagnosis is possible. In individuals with Cat-Eye syndrome, the short arm and a small region of the long arm of chromosome 22 (i.e.,... Read More

Risk factors of clinical dysimmune manifestations in children with 22q11.2 deletion syndrome
Risk factors of clinical dysimmune manifestations in a cohort of 86 children with 22q11.2 deletion syndrome: A retrospective study in France 22q11.2 deletion syndrome is one of the most common microdeletion syndromes. Patients with this syndrome have a higher risk of infections, autoimmune diseases, and allergies. Deletions that include the... Read More

Genotypic and phenotypic variability of chromosome 22q11.2 microduplications
Genotypic and phenotypic variability of 22q11.2 microduplications: An institutional experience 22q11.2 region is rich in low copy repeats (large repetitive blocks of DNA that are similar to each other), which makes the region prone to both deletions and duplications during meiosis. Deletions of 22q11.2 are very common. Microduplications of this... Read More

Neuropsychiatric phenotypes and ASD features in 3q29 deletion syndrome
Neuropsychiatric phenotypes and a distinct constellation of ASD features in 3q29 deletion syndrome: results from the 3q29 registry The phenotype of 3q29 deletion syndrome is characterized mainly by neurodevelopmental and psychiatric features. Usually this syndrome is caused by a de novo deletion, typically 1.6 Mb, on chromosome 3. Although, it... Read More
