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 Benign. Variant got -7 ACMG points.

• PM4: Stoplost variant in NM_004833.3 Downstream stopcodon found after 8 codons.
• BP6: Variant 1-159062694-A-C is Benign according to our data. Variant chr1-159062694-A-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 780267.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0106 (1608/151322) while in subpopulation AFR AF= 0.0362 (1493/41200). AF 95% confidence interval is 0.0347. There are 24 homozygotes in gnomad4. There are 765 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 24 AR gene
