Article Synopsis
- ARID1A and ARID1B duplications are linked to Coffin-Siris syndrome, but ARID1B duplications have not been previously associated with a specific clinical phenotype until now.
- A study analyzed 16 cases of ARID1A and 13 cases of ARID1B duplications, revealing that ARID1A duplications resulted in more severe symptoms, including intellectual disabilities and growth delays, while both groups displayed similar features.
- The research identified unique DNA methylation patterns in ARID1A duplication patients, which differ from those with loss-of-function variants, suggesting the presence of a distinct clinical phenotype for both ARID1A and ARID1B duplications, indicating a new type of
Background: Current guidelines indicate that patients with extreme oligozoospermia or azoospermia should be tested for chromosomal imbalances, azoospermia factor (AZF) deletions and/or CFTR variants. For other sperm abnormalities, no genetic diagnostics are recommended.
Objectives: To determine whether exome sequencing (ES) with combined copy number variant (CNV) and single nucleotide variant (SNV) analysis is a reliable first-tier method to replace current methods (validation study), and to evaluate the diagnostic yield after 10 months of implementation (evaluation study).
Background: Vascular Ehlers-Danlos syndrome (vEDS) is a rare connective tissue disorder with a high risk for arterial, bowel, and uterine rupture, caused by heterozygous pathogenic variants in . The aim of this cohort study is to provide further insights into the natural history of vEDS and describe genotype-phenotype correlations in a Dutch multicenter cohort to optimize patient care and increase awareness of the disease.
Methods: Individuals with vEDS throughout the Netherlands were included.
Our case report documents the first type A aortic dissection in a patient with Kabuki syndrome (KS) and emphasize the need for intensive cardiovascular risk monitoring in patients with KS. It stresses the importance of further research to establish a correlation and awareness for patients with KS.
