Pathogenic variants in the EPM2A gene are associated with 22-70% of clinical cases of Lafora type progressive myoclonus epilepsy.
The cell is continually producing essential building blocks for life, such as proteins, metabolites, sugars, and lipids. These components are also continually degraded as they become damaged, overabundant, or unnecessary. If this balance is disrupted, then excess components can accumulate in the cell, interfering with normal function and causing toxicity. The EPM2A gene encodes a protein of largely unknown function called laforin. It is thought to play a role in sugar metabolism, as loss of EPM2A expression is correlated with the accumulation of insoluble carbohydrate deposits in cells throughout the body, including neurons (PMID: 17915579).
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.
