6 genes linked to Long palm

Changes in these genes cause rare conditions in which Long palm 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
TBCBtubulin folding cofactor B	Always	In 1 condition
PORcytochrome p450 oxidoreductase	Sometimes (5–29%)	In 1 condition
SLC2A10solute carrier family 2 member 10	Sometimes (5–29%)	In 1 condition
UPF3BUPF3B regulator of nonsense mediated mRNA decay	Sometimes (5–29%)	In 1 condition
SMSspermine synthase	Not recorded	In 1 condition
UBE3Bubiquitin protein ligase E3B	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.
