Invitae tests that include this gene:

ITGA7 is a rare cause of congenital muscular dystrophy, and the percentage of cases attributed to pathogenic variants in ITGA7 is unknown.

ITGA7 encodes Integrin alpha-7, a subunit of the ITGA7/Beta-1 integrin complex, which itself is a receptor for Laminin-2 in the extracellular space. ITGA7 is expressed in skeletal and cardiac muscle and may be important for myogenesis, cell migration, and differentiation.

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.
