LAMA4

Alias

-1; CMD1JJ; LAMA3; LAMA4

Associated disorders

The LAMA4 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal dominant dilated cardiomyopathy (DCM) (MedGen UID: 815265).

Invitae tests that include this gene:

Pathogenic LAMA4 variants are associated with an unknown percentage of clinical cases of DCM.

The LAMA4 gene encodes alpha-laminin 4, which is a variant A chain of laminin, a multidomain glycoprotein that is a primary component of basement membranes in the heart and blood vessels.

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 in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

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.
