Genes affected

OTULIN (HGNC:25118): (OTU deubiquitinase with linear linkage specificity) This gene encodes a member of the peptidase C65 family of ubiquitin isopeptidases. Members of this family remove ubiquitin from proteins. The encoded enzyme specifically recognizes and removes M1(Met1)-linked, or linear, ubiquitin chains from protein substrates. Linear ubiquitin chains are known to regulate the NF-kappa B signaling pathway in the context of immunity and inflammation. Mutations in this gene cause a potentially fatal autoinflammatory syndrome in human patients. [provided by RefSeq, Sep 2016]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-14687568-AC-A is Pathogenic according to our data. Variant chr5-14687568-AC-A is described in ClinVar as [Pathogenic, risk_factor]. Clinvar id is 254125.Status of the report is no_assertion_criteria_provided, 0 stars.
