ARVD11; CDHF2; DG2; DGII; DSC3; III
The DSC2 gene is associated with autosomal dominant arrhythmogenic right ventricular cardiomyopathy (ARVC) (MedGen UID: 351237) and autosomal recessive ARVC with palmoplantar keratoderma and woolly hair (OMIM: 125645).

Pathogenic DSC2 variants are associated with 1%-13% of clinical cases of ARVC.
The DSC2 gene encodes the protein desmocollin-2. This protein is part of the desmosome complex, which is present in both muscle and skin cells. The primary role of the desmosome is to adhere cells to each other, thus maintaining the structural integrity of skin and muscle tissues. Pathogenic variants in genes encoding cardiac-specific desmosome proteins are a common cause of arrhythmogenic right ventricular cardiomyopathy.
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.
