Genes affected

COMMD3 (HGNC:23332): (COMM domain containing 3) Predicted to be involved in sodium ion transport. Predicted to be located in extracellular region and ficolin-1-rich granule lumen. [provided by Alliance of Genome Resources, Apr 2022]

COMMD3-BMI1 (HGNC:48326): (COMMD3-BMI1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring COMM domain-containing protein 3 and polycomb complex protein BMI-1 genes on chromosome 10. The read-through transcript produces a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Feb 2011]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
