7 genes linked to Atlantoaxial dislocation

Changes in these genes cause rare conditions in which Atlantoaxial 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
NFIXnuclear factor I X	Often (30–79%)	In 1 condition
RMRPRNA component of mitochondrial RNA processing endoribonuclease	Often (30–79%)	In 1 condition
B3GALT6beta-1,3-galactosyltransferase 6	Sometimes (5–29%)	In 1 condition
CHST14carbohydrate sulfotransferase 14	Sometimes (5–29%)	In 1 condition
DSEdermatan sulfate epimerase	Sometimes (5–29%)	In 1 condition
COMPcartilage oligomeric matrix protein	Not recorded	In 1 condition
GNPTABN-acetylglucosamine-1-phosphate transferase subunits alpha and beta	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.
