Genes affected

TYK2 (HGNC:12440): (tyrosine kinase 2) This gene encodes a member of the tyrosine kinase and, more specifically, the Janus kinases (JAKs) protein families. This protein associates with the cytoplasmic domain of type I and type II cytokine receptors and promulgate cytokine signals by phosphorylating receptor subunits. It is also a component of both the type I and type III interferon signaling pathways. As such, it may play a role in anti-viral immunity. A mutation in this gene has been associated with Immunodeficiency 35. [provided by RefSeq, Sep 2020]

ACMG classification

Verdict is Benign. Variant got -11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 19-10365718-G-A is Benign according to our data. Variant chr19-10365718-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 536650.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr19-10365718-G-A is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-1.05 with no splicing effect.
