4 genes linked to Breath-holding spell

Changes in these genes cause rare conditions in which Breath-holding spell 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
HIVEP2HIVEP zinc finger 2	Always	In 1 condition
RNU2-2RNA, U2 small nuclear 2	Always	In 1 condition
WDR83OSWD repeat domain 83 opposite strand	Always	In 1 condition
FGFR2fibroblast growth factor receptor 2	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.
