Dante Labs condition reports look at the genes behind groups of inherited conditions, read from one whole-genome test. Each page says which conditions and genes a report covers, how it is read and what it cannot tell you.

Get my Genome Test23 genes linked to Unequal size of red blood cells
Changes in these genes cause rare conditions in which Unequal size of red blood cells is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.

How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
