Trait
Partial knee cap dislocation
Clinical name: Patellar subluxation
The kneecap normally is located within the groove termed trochlea on the distal femur and can slide up and down in it. Patellar subluxation refers to an unstable kneecap that does not slide centrally within its groove, i.e., a partial dislocation of the patella.

Changes in these genes cause rare conditions in which Partial knee cap dislocation 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 |
|---|---|---|
| DSTdystonin | Always | In 1 condition |
| TBC1D7TBC1 domain family member 7 | Always | In 1 condition |
| FBN2fibrillin 2 | Often (30–79%) | In 1 condition |
| COL12A1collagen type XII alpha 1 chain | Sometimes (5–29%) | In 1 condition |
| DNMT3ADNA methyltransferase 3 alpha | Sometimes (5–29%) | In 1 condition |
| USP9Xubiquitin specific peptidase 9 X-linked | Sometimes (5–29%) | In 1 condition |
| YY1YY1 transcription factor | Sometimes (5–29%) | In 1 condition |
| WNK3WNK lysine deficient protein kinase 3 | Not recorded | 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.
