Genes affected

IRF5 (HGNC:6120): (interferon regulatory factor 5) This gene encodes a member of the interferon regulatory factor (IRF) family, a group of transcription factors with diverse roles, including virus-mediated activation of interferon, and modulation of cell growth, differentiation, apoptosis, and immune system activity. Members of the IRF family are characterized by a conserved N-terminal DNA-binding domain containing tryptophan (W) repeats. Alternative promoter use and alternative splicing result in multiple transcript variants, and a 30-nt indel polymorphism (SNP rs60344245) can result in loss of a 10-aa segment.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.97).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0154 (2352/152234) while in subpopulation NFE AF = 0.0235 (1599/68006). AF 95% confidence interval is 0.0226. There are 29 homozygotes in GnomAd4. There are 1164 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 29 Unknown gene
