3 genes linked to Congenital aphakia

Changes in these genes cause rare conditions in which Congenital aphakia 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.

Gene	How often it is seen	Conditions
FOXE3forkhead box E3	Very often (80–99%)	In 2 conditions
TONSLtonsoku like, DNA repair protein	Sometimes (5–29%)	In 1 condition
MT-CYBmitochondrially encoded cytochrome b	Rarely (1–4%)	In 1 condition

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.
