Genes affected

TNFAIP2 (HGNC:11895): (TNF alpha induced protein 2) This gene was identified as a gene whose expression can be induced by the tumor necrosis factor alpha (TNF) in umbilical vein endothelial cells. The expression of this gene was shown to be induced by retinoic acid in a cell line expressing a oncogenic version of the retinoic acid receptor alpha fusion protein, which suggested that this gene may be a retinoic acid target gene in acute promyelocytic leukemia.

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.047738135).

Sep 12, 2023

The c.67G>A (p.E23K) alteration is located in exon 1 (coding exon 1) of the TNFAIP2 gene. This alteration results from a G to A substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
