Genes affected

POU2AF3 (HGNC:26978): (POU class 2 homeobox associating factor 3) Located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

COLCA1 (HGNC:33789): (colorectal cancer associated 1) This gene encodes a transmembrane protein that localizes to granular structures, including crystalloid eosinophilic granules and other granular organelles. This gene, along with an overlapping opposite strand gene, has been implicated as a susceptibility locus for colorectal cancer. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Nov 2014]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0030952394).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.806 is higher than 0.05.
