Genes affected

TRAF3IP3 (HGNC:30766): (TRAF3 interacting protein 3) The gene encodes a protein that mediates cell growth by modulating the c-Jun N-terminal kinase signal transduction pathway. The encoded protein may also interact with a large multi-protein assembly containing the phosphatase 2A catalytic subunit. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.39155465).

The c.743C>G (p.S248C) alteration is located in exon 9 (coding exon 7) of the TRAF3IP3 gene. This alteration results from a C to G substitution at nucleotide position 743, causing the serine (S) at amino acid position 248 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
