Genes affected

NLRP13 (HGNC:22937): (NLR family pyrin domain containing 13) This gene encodes a member of the NACHT, leucine rich repeat, and PYD containing (NLRP) protein family. It has an N-terminal pyrin domain, followed by a NACHT domain, a NACHT-associated domain (NAD), and a C-terminal leucine-rich repeat (LRR) region. NLRP proteins are implicated in the activation of proinflammatory caspases through multiprotein complexes called inflammasomes. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

The c.2433C>A (p.N811K) alteration is located in exon 7 (coding exon 7) of the NLRP13 gene. This alteration results from a C to A substitution at nucleotide position 2433, causing the asparagine (N) at amino acid position 811 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
