Associated disorders

The NR2F2 gene is associated with autosomal dominant congenital heart defects (MedGen UID: 777001) and heterotaxy (MedGen UID: 336609).

The percentage of congenital heart defects attributed to pathogenic variants identified in the NR2F2 gene is unknown.

The NR2F2 gene encodes a transcription factor (also called COUP-TFII) that can both activate and repress gene expression through a variety of mechanisms. NR2F2 is expressed in every human tissue tested thus far, but mice that lack this gene succumb to defects in the cardiovascular system, suggesting that this gene is important in heart development during embryogenesis.

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.
