The BSCL2 gene is associated with a spectrum of autosomal dominant neurological conditions, including Charcot-Marie-Tooth disease type 2 (CMT2) (PMID: 15732094), distal hereditary motor neuropathy type 5 (HMN5) (MedGen UID: 318838), and spastic paraplegia 17 (SPG17), also known as Silver syndrome (MedGen UID: 442302). It is also associated with autosomal recessive congenital generalized lipodystrophy, type 2 (CGL2) (MedGen UID: 318593).

Pathogenic variants in BSCL2 genes cause a spectrum of neurological disorders. It is the sole causative gene of autosomal recessive congenital generalized lipodystrophy type 2. It has also been associated with HSP, dMHN, and CMT phenotypes but is a rare cause of these disorders.
The BSCL2 gene encodes a protein called seipin. Althought its precise function is unknown, seipin is highly expressed in motor neurons of the spinal cord, cortical neurons of the brain, adipose tissue, and the testis.
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.
