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]

The c.371T>A (p.I124N) alteration is located in exon 4 (coding exon 3) of the NLRC4 gene. This alteration results from a T to A substitution at nucleotide position 371, causing the isoleucine (I) at amino acid position 124 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
