The CYP7B1 gene is associated with autosomal recessive hereditary spastic paraplegia type 5A (SPG5A) (MedGen UID: 376521) and autosomal recessive congenital bile acid synthesis defect type 3 (CBAS3) (MedGenUID: 462497).

Invitae tests that include this gene:
An estimated 6%-7% of autosomal recessive HSP is caused by pathogenic variants identified in CYP7B1.
The CYP7B1 gene encodes a member of the cytochrome P450 superfamily of enzymes, which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This enzyme is thought to plays a role in bile acid synthesis, neurosteroid metabolism, the development of atherosclerosis and sex hormone synthesis.
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.
