Genetic Variant TRAF3IP1:p.Pro30His (chr2-238320751-C-A) – ACMG Classification: Uncertain_significance (3 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3

The NM_015650.4(TRAF3IP1):c.89C>A(p.Pro30His) variant causes a missense change. The variant allele was found at a frequency of 0.00000155 in 1,289,282 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P30S) has been classified as Uncertain significance.

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]
