Changes in these genes cause rare conditions in which CSF pleocytosis 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.

|---|---|---|
| CMPK2cytidine/uridine monophosphate kinase 2 | Always | In 1 condition |
| DCLRE1CDNA cross-link repair 1C | Always | In 1 condition |
| LSM11LSM11, U7 small nuclear RNA associated | Always | In 1 condition |
| RAG1recombination activating 1 | Always | In 1 condition |
| RAG2recombination activating 2 | Always | In 1 condition |
| FASFas cell surface death receptor | Very often (80–99%) | 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.
