Invitae tests that include this gene:
Pathogenic variants in RAC2 are a rare cause of common variable immunodeficiency (CVID). At this time, the percentage of CVID that can be attributed to pathogenic variants in RAC2 is unknown. Pathogenic variants in RAC2 are a rare cause of neutrophil immunodeficiency syndrome. At this time, the percentage of neutrophil immunodeficiency syndrome that can be attributed to pathogenic variants in RAC2 is unknown.
The RAC2 gene encodes a member of the Rho GTPases, a group of small signaling molecules that activate various cellular signaling pathways leading to events such as actin polymerization and the formation of a reduced NADPH oxidase complex. In leukocytes, Rho GTPases participate in the tightly controlled process of transendothelial migration as well as chemotaxis in response to immune system stimulation (PMID: 21178276).
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
