Genes affected

NLRP1 (HGNC:14374): (NLR family pyrin domain containing 1) This gene encodes a member of the Ced-4 family of apoptosis proteins. Ced-family members contain a caspase recruitment domain (CARD) and are known to be key mediators of programmed cell death. The encoded protein contains a distinct N-terminal pyrin-like motif, which is possibly involved in protein-protein interactions. This protein interacts strongly with caspase 2 and weakly with caspase 9. Overexpression of this gene was demonstrated to induce apoptosis in cells. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene, but the biological validity of some variants has not been determined.

Collection Method:clinical testing

The c.4358C>T (p.P1453L) alteration is located in exon 17 (coding exon 17) of the NLRP1 gene. This alteration results from a C to T substitution at nucleotide position 4358, causing the proline (P) at amino acid position 1453 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature in individuals affected with NLRP1-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1453 of the NLRP1 protein (p.Pro1453Leu). -
