SGCD

Alias

35DAG; CMD1L; DAGD; SG-delta; SGCDP; SGD

Associated disorders

The SGCD gene is associated with autosomal recessive limb-girdle muscular dystrophy type 2F (LGMD2F) (MedGen UID: 331308). Additionally, the SGCD gene has preliminary evidence supporting a correlation with isolated autosomal dominant dilated cardiomyopathy (DCM) (MedGen UID: 335735).

Pathogenic variants in SGCD are estimated to cause less than 1% of clinical cases of LGMD.

The SGCD gene encodes the delta-sarcoglycan protein, a subunit of the tetrameric sarcoglycan complex. The sarcoglycan complex is a component of the dystrophin-glycoprotein complex, which functions as a structural link between the cytoskeleton of muscle cells and the extracellular matrix.

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.
