The PREPL gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal recessive congenital myasthenic syndrome (CMS) (PMID: 24610330).

Invitae tests that include this gene:
PREPL is a very rare cause of congenital myasthenic syndrome, and the percentage of cases attributed to pathogenic variants in PREPL is unknown.
PREPL encodes a member of the prolyl oligopeptidase subfamily of serine peptidases. Although the function of PREPL is not completely understood, it is known that PREPL acts as an effector of the clathrin-associated adaptor protein-1 (AP-1). Because AP-1 is required for transport of acetycholine-containing vesicles to the cytosol, loss of PREPL activity could negatively impact neuromuscular transmission.
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.
