2-238320713-T-G

Position:

• chr2-238320713-T-G

Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2 PM5 PP5

The NM_015650.4(TRAF3IP1):​c.51T>G​(p.Ile17Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I17S) has been classified as Likely pathogenic.

Genes affected

TRAF3IP1 (HGNC:17861): (TRAF3 interacting protein 1) The protein encoded by this gene interacts with TNF receptor-associated factor 3, tethering it to cytoskeletal microtubules. The encoded protein is also an inhibitor of the innate type I IFN response. Defects in this gene are a cause of Senior-Loken syndrome 9. [provided by RefSeq, Mar 2017]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP5: Variant 2-238320713-T-G is Pathogenic according to our data. Variant chr2-238320713-T-G is described in ClinVar as [Pathogenic]. Clinvar id is 254150.Status of the report is no_assertion_criteria_provided, 0 stars.
