Genes affected
NLRC4 (HGNC:16412): (NLR family CARD domain containing 4) This gene encodes a member of the caspase recruitment domain-containing NLR family. Family members play essential roles in innate immune response to a wide range of pathogenic organisms, tissue damage and other cellular stresses. Mutations in this gene result in autoinflammation with infantile enterocolitis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.871G>A (p.G291S) alteration is located in exon 4 (coding exon 3) of the NLRC4 gene. This alteration results from a G to A substitution at nucleotide position 871, causing the glycine (G) at amino acid position 291 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 291 of the NLRC4 protein (p.Gly291Ser). This variant is present in population databases (rs780335164, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with NLRC4-related conditions. ClinVar contains an entry for this variant (Variation ID: 575189). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt NLRC4 protein function with a positive predictive value of 80%. 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. -
