Associated disorders

The NLRP3 gene is associated with autosomal dominant cryopyrin-associated periodic syndrome (MedGen UID: 412215).

Invitae tests that include this gene:

Pathogenic variants in the NLRP3 gene are the only known cause of cryopyrin-associated periodic syndrome.

The NLRP3 gene encodes a pyrin-like protein containing a pyrin domain, a nucleotide-binding site domain, and a leucine rich repeat motif. The pyrin-like protein plays a role in the regulation of inflammation, the immune response, and apoptosis. Pyrin-like protein forms a complex with the apoptosis-associated speck-like protein PYCARD/ASC that functions as an upstream activator of NF-kappaB signaling.

Assay and technical information

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.
