Changes in these genes cause rare conditions in which Developmental stagnation 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.

|---|---|---|
| ACER3alkaline ceramidase 3 | Always | In 1 condition |
| GABBR2gamma-aminobutyric acid type B receptor subunit 2 | Always | In 2 conditions |
| PTPN23protein tyrosine phosphatase non-receptor type 23 | Always | In 1 condition |
| MCOLN1mucolipin TRP cation channel 1 | Very often (80–99%) | In 2 conditions |

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.
