Genes affected

IL22 (HGNC:14900): (interleukin 22) This gene is a member of the IL10 family of cytokines that mediate cellular inflammatory responses. The encoded protein functions in antimicrobial defense at mucosal surfaces and in tissue repair. This protein also has pro-inflammatory properties and plays a role in in the pathogenesis of several intestinal diseases. The encoded protein is a crucial cytokine that regulates host immunity in infectious diseases, including COVID-19 (disease caused by SARS-CoV-2). [provided by RefSeq, Dec 2021]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0072984397).
• BP6: Variant 12-68248867-T-C is Benign according to our data. Variant chr12-68248867-T-C is described in ClinVar as [Benign]. Clinvar id is 709289.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00735 (1120/152298) while in subpopulation AFR AF= 0.0256 (1062/41556). AF 95% confidence interval is 0.0243. There are 10 homozygotes in gnomad4. There are 511 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 10 AR gene
