Test description

The Invitae Congenital Heart Disease Panel analyzes 40 genes that are associated with both isolated and syndromic congenital heart defects.

This test may establish a genetic diagnosis, which would eliminate the need for serial gene testing. A genetic diagnosis may guide medical management, enabling a clinician to determine the need for additional evaluations, screenings, and procedures.

Alternative tests to consider

There can be significant clinical overlap between heterotaxy and congenital heart disease. The Invitae Congenital Heart Disease Panel includes some genes associated with heterotaxy that have specifically been linked to congenital heart defects. The Invitae Congenital Heart Disease and Heterotaxy Panel is a comprehensive test for congenital heart disease with additional genes associated with situs inversus or heterotaxy, and depending on your patient’s clinical presentation, this panel may be more appropriate. The Invitae Congenital Heart Disease and Heterotaxy Panel cannot be combined with other cardiology panels either at initial order or re-requisition.

Congenital heart disease—more commonly referred to as congenital heart defects (CHD)—is the most common birth defect, affecting 35,000-40,000 newborns each year in the US. It is a leading cause of childhood morbidity and mortality worldwide. CHD can occur in isolation or within a constellation of symptoms comprising a genetic syndrome.

The clinical sensitivity for this test is unknown. Structural heart defects are clinically and genetically heterogeneous, and the percentage of patients with congenital heart disease and a pathogenic variant in one of the genes offered in this panel has not been determined.

Congenital heart disease can be inherited in several patterns, including autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive.

The penetrance, symptoms and associated risks of congenital heart defects depend upon the specific variants in the identified gene.

Congenital heart disease affects approximately 8–10 per 1,000 live births and is the single largest cause of infant morbidity and mortality worldwide. Epidemiologic studies suggest that a genetic or environmental cause for CHD is identifiable in approximately 20%–30% of cases, with 3%–5% of CHD due to a detectable single-gene disorder. The combined prevalence of the disorders tested for in this panel has not been determined.

This test may be considered for individuals who have congenital heart defects with or without additional congenital anomalies or syndromic features.

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.
