Associated disorders

The DCLRE1C gene is associated with autosomal recessive severe combined immune deficiency with sensitivity to ionizing radiation (MedGen UID: 355454).

An estimated 4% of severe combined immunodeficiency (SCID) is caused by pathogenic variants identified in DCLRE1C (PMID: 25138334).

DCLRE1C encodes the artemis endonuclease, which is involved in repairing double strand DNA breaks, a process that is also important for V(D)J recombination. V(D)J recombination is an essential step in the normal development of B-cells and T-cells. Artemis is also involved in DNA damage repair as part of cell cycle regulation (PMID: 24230999, 26476407).

Assay and technical information

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, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

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.
