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 Impaired homooligomerization. (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=0.04997036).

The c.136A>G (p.I46V) alteration is located in exon 2 (coding exon 1) of the AIM2 gene. This alteration results from a A to G substitution at nucleotide position 136, causing the isoleucine (I) at amino acid position 46 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
