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]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.91).
BP6
Variant 2-32249608-C-T is Benign according to our data. Variant chr2-32249608-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 542052.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.05 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000565 (86/152160) while in subpopulation AFR AF = 0.00188 (78/41510). AF 95% confidence interval is 0.00154. There are 0 homozygotes in GnomAd4. There are 45 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 86 AD gene.
