prediction, molecular modeling, and dynamics studies on the targeted next-generation sequencing identified genes underlying congenital heart disease in Down syndrome patients.

Background: Individuals with Down syndrome (DS) have a 40%-60% chance of being born with congenital heart disease (CHD). This indicates that CHD in individuals with DS is not solely caused by trisomy 21, and there may be other genetic factors contributing to the development of CHD in these children. A study has identified variants in the specific genes that contribute to the pathogenesis of CHD in children with DS, isolated DS, and the CHD group.

The Polymorphism at the microRNA-155 Binding Site in the AGTR1 Gene is not Significantly Associated with Rheumatic Heart Disease in Saudi Arabia Population.

Background: Rheumatic Heart Disease (RHD) remains a major cause of cardiovascular diseases and the most devastating effects are shown on children and young adults. RHD is caused due to the interaction between microbial, environmental, immunologic, and genetic factors. The Renin- Angiotensin Aldosterone System (RAAS) has been strongly implicated as the susceptibility pathway in the pathogenesis of the cardiovascular disease.
