Genes affected

OTUD5 (HGNC:25402): (OTU deubiquitinase 5) This gene encodes a member of the OTU (ovarian tumor) domain-containing cysteine protease superfamily. The OTU domain confers deubiquitinase activity and the encoded protein has been shown to suppress the type I interferon-dependent innate immune response by cleaving the polyubiquitin chain from an essential type I interferon adaptor protein. Cleavage results in disassociation of the adaptor protein from a downstream signaling complex and disruption of the type I interferon signaling cascade. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Oct 2008]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), OTUD5. . Gene score misZ 3.994 (greater than the threshold 3.09). GenCC has associacion of gene with multiple congenital anomalies-neurodevelopmental syndrome, X-linked, multiple congenital anomalies/dysmorphic syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.09945747).
• BS2: High Hemizygotes in GnomAdExome4 at 7 XL gene

The c.1418T>C (p.M473T) alteration is located in exon 7 (coding exon 7) of the OTUD5 gene. This alteration results from a T to C substitution at nucleotide position 1418, causing the methionine (M) at amino acid position 473 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
