4 genes linked to Congenital drooping upper eyelid

Changes in these genes cause rare conditions in which Congenital drooping upper eyelid 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.

GeneHow often it is seenConditions
WSB2WD repeat and SOCS box containing 2AlwaysIn 1 condition
BRCC3BRCA1/BRCA2-containing complex subunit 3Often (30–79%)In 1 condition
DNA2DNA replication helicase/nuclease 2Often (30–79%)In 1 condition
TRIOtrio Rho guanine nucleotide exchange factorSometimes (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.
