Invitae tests that include this gene:
Pathogenic variants in the PNKP gene are a rare cause of clinical cases of early infantile epileptic encephalopathy (EIEE).
DNA is regularly damaged by both intracellular and extracellular insults, and needs to be repaired in order to maintain genome integrity. The PNKP gene encodes a DNA repair enzyme that uses its catalytic activities to ensure that the DNA termini remaining after removal of a DNA lesion are compatible with extension and ligation, priming the area for repair (PMID: 21353781).
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.
