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]

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.021336168).
• BP6: Variant 2-32238296-C-A is Benign according to our data. Variant chr2-32238296-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 475252.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0024 (366/152212) while in subpopulation NFE AF = 0.00423 (288/68032). AF 95% confidence interval is 0.00383. There are 4 homozygotes in GnomAd4. There are 156 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High AC in GnomAd4 at 366 AD gene.
