Changes in these genes cause rare conditions in which Mediastinal mass 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 |
|---|---|---|
| BCL2BCL2 apoptosis regulator | Rarely (1–4%) | In 1 condition |
| BCL6BCL6 transcription repressor | Rarely (1–4%) | In 1 condition |
| HLA-DRB1major histocompatibility complex, class II, DR beta 1 | Rarely (1–4%) | In 1 condition |
| IGHimmunoglobulin heavy locus | Rarely (1–4%) | In 1 condition |
| KIF1Bkinesin family member 1B | 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.
