ACTA2

actin alpha 2, smooth muscle

This gene encodes one of six different actin proteins. Actins are highly conserved proteins that are involved in cell motility, structure, integrity, and intercellular signaling. The encoded protein is a smooth muscle actin that is involved in vascular contractility and blood pressure homeostasis. Mutations in this gene cause a variety of vascular diseases, such as thoracic aortic disease, coronary artery disease, stroke, and Moyamoya disease, as well as multisystemic smooth muscle dysfunction syndrome.

AD Risk Scores

About AD Risk Scores

The TREAT-AD Center at Emory-Sage-SGC has developed a Target Risk Score (TRS) to objectively rank the potential involvement of specific genes in AD. The TRS is derived by summing two component risk scores, the Genetic Risk Score and the Multi-omic Risk Score, each of which is derived from a meta-analysis of multiple harmonized data sets. More information about the methodology used to define these risk scores is available here.

AD Risk Scores for ACTA2

The TRS for ACTA2, along with the component Genetic and Multi-omic Risk Scores, is shown here. The scores for ACTA2 are superimposed on the genome-wide score distributions. If No Data is Currently Available is displayed for a score, that score was not calculated for ACTA2.

Biological Domain Classification

About Biological Domains

A biological domain represents a standardized area of biology defined by a set of discrete, biologically coherent GO terms. The TREAT-AD Center at Emory-Sage-SGC has defined nineteen biological domains associated with AD, and objectively mapped genes to those biological domains using GO term annotations. More information about the methodology used to define AD biological domains, and to generate genome-wide biological domain mappings, is available here.

Biological Domains for ACTA2

Select a biological domain on the left to see the list of GO terms that link ACTA2 to it on the right. The percentage value displayed next to the currently selected biological domain indicates the proportion of ACTA2's total unique GO terms that map to the biological domain. The ratio displayed on the right indicates how many of the biological domain's total GO terms ACTA2 is annotated with.
