6 genes linked to Normal pressure hydrocephalus

Changes in these genes cause rare conditions in which Normal pressure hydrocephalus 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
SCN4Asodium voltage-gated channel alpha subunit 4	Always	In 1 condition
SPIN4spindlin family member 4	Always	In 1 condition
TUBB3tubulin beta 3 class III	Sometimes (5–29%)	In 1 condition
CFAP43cilia and flagella associated protein 43	Not recorded	In 1 condition
ERCC6ERCC excision repair 6, chromatin remodeling factor	Not recorded	In 1 condition
ERCC8ERCC excision repair 8, CSA ubiquitin ligase complex subunit	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.
