Genes affected

AIM2 (HGNC:357): (absent in melanoma 2) AIM2 is a member of the IFI20X /IFI16 family. It plays a putative role in tumorigenic reversion and may control cell proliferation. Interferon-gamma induces expression of AIM2. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM1: In a mutagenesis_site Strongly reduced ability to homooligomerize upon double-stranded DNA (dsDNA)-binding. (size 0) in uniprot entity AIM2_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.049512982).

The c.439G>A (p.E147K) alteration is located in exon 4 (coding exon 3) of the AIM2 gene. This alteration results from a G to A substitution at nucleotide position 439, causing the glutamic acid (E) at amino acid position 147 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
