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]

Ambry Genetics

Oct 18, 2021

The c.255G>A (p.M85I) alteration is located in exon 3 (coding exon 3) of the IL22 gene. This alteration results from a G to A substitution at nucleotide position 255, causing the methionine (M) at amino acid position 85 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
