Changes in these genes cause rare conditions in which Small lymph nodes 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 |
|---|---|---|
| EPHB4EPH receptor B4 | Often (30–79%) | In 1 condition |
| IL2RGinterleukin 2 receptor subunit gamma | Sometimes (5–29%) | In 1 condition |
| BTKBruton tyrosine kinase | Not recorded | In 1 condition |
| DCLRE1CDNA cross-link repair 1C | Not recorded | In 1 condition |
| PNPpurine nucleoside phosphorylase | 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.
