10 genes linked to Long neck

Changes in these genes cause rare conditions in which Long neck 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
DONSONDNA replication fork stabilization factor DONSON	Always	In 1 condition
EBPEBP cholestenol delta-isomerase	Always	In 2 conditions
HERC1HECT and RLD domain containing E3 ubiquitin protein ligase family member 1	Always	In 2 conditions
RNU2-2RNA, U2 small nuclear 2	Always	In 1 condition
POLR3ARNA polymerase III subunit A	Often (30–79%)	In 1 condition
GABRA3gamma-aminobutyric acid type A receptor subunit alpha3	Sometimes (5–29%)	In 1 condition
RNU4-2RNA, U4 small nuclear 2	Rarely (1–4%)	In 1 condition
ATP7AATPase copper transporting alpha	Not recorded	In 1 condition
EYA1EYA transcriptional coactivator and phosphatase 1	Not recorded	In 1 condition
FLNAfilamin A	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.
