Genes affected

IL23A (HGNC:15488): (interleukin 23 subunit alpha) This gene encodes a subunit of the heterodimeric cytokine interleukin 23 (IL23). IL23 is composed of this protein and the p40 subunit of interleukin 12 (IL12B). The receptor of IL23 is formed by the beta 1 subunit of IL12 (IL12RB1) and an IL23 specific subunit, IL23R. Both IL23 and IL12 can activate the transcription activator STAT4, and stimulate the production of interferon-gamma (IFNG). In contrast to IL12, which acts mainly on naive CD4(+) T cells, IL23 preferentially acts on memory CD4(+) T cells. [provided by RefSeq, Jul 2008]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00496 (754/152070) while in subpopulation AFR AF = 0.0172 (715/41518). AF 95% confidence interval is 0.0162. There are 9 homozygotes in GnomAd4. There are 351 alleles in the male GnomAd4 subpopulation. Median coverage is 29. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 9 gene
