The variant received -2 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_Strong

The NM_138348.6(OTULIN):c.44C>A (p.Ala15Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.A15= (synonymous): Likely_benign (ClinVar VariationId 3613133, 1 star)

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]

Classification according to ACMG Germline Pathogenicity v2019

Our verdict: Likely_benign. The variant received -2 points.

• PM2: Absent from gnomAD (AD/XL gene) — PM2; Absent from gnomAD at well-covered site (MOI: AD+AR) (threshold 0.0001) — PM2 moderate.
• BP4: Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Strong).
