5 genes linked to Cleft earlobe

Changes in these genes cause rare conditions in which Cleft earlobe 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
CAPRIN1cell cycle associated protein 1	Sometimes (5–29%)	In 1 condition
COX7Bcytochrome c oxidase subunit 7B	Sometimes (5–29%)	In 1 condition
HCCSholocytochrome c synthase	Sometimes (5–29%)	In 1 condition
MAN2C1mannosidase alpha class 2C member 1	Sometimes (5–29%)	In 1 condition
NDUFB11NADH:ubiquinone oxidoreductase subunit B11	Sometimes (5–29%)	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.
