BTHLM1; OPLL; UCHMD1
The COL6A1 gene is associated with autosomal dominant and recessive Bethlem myopathy 1 (BTHLM1) (MedGen UID: 331805) and Ullrich congenital muscular dystrophy 1 (UCMD1) (MedGen UID: 98046), collectively known as type VI collagenopathies (MedGen UID: 468393).

Invitae tests that include this gene:
Pathogenic variants in COL6A1 are estimated to account for 38% of type VI collagenopathy cases.
Type VI collagen is composed of three chains: alpha1(VI), alpha2(VI), and alpha3(VI). COL6A1, located on chromosome 21q22.3, encodes the alpha1(VI) chain. Collagen VI is found in connective tissue and forms a microfibrillar network, functioning to anchor the basement membrane to the extracellular matrix.
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.
