Changes in these genes cause rare conditions in which Tapered sperm head 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 |
|---|---|---|
| ACTL9actin like 9 | Always | In 1 condition |
| ARMC2armadillo repeat containing 2 | Always | In 1 condition |
| CATIPciliogenesis associated TTC17 interacting protein | Always | In 1 condition |
| CFAP206cilia and flagella associated protein 206 | Always | In 1 condition |
| CFAP70cilia and flagella associated protein 70 | Always | In 1 condition |
| IQCNIQ motif containing N | Always | In 1 condition |
| CFAP69cilia and flagella associated protein 69 | Not recorded | In 1 condition |
| DNAH17dynein axonemal heavy chain 17 | Not recorded | In 1 condition |
| TTC29tetratricopeptide repeat domain 29 | 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.
