Trait
Suck reflex
A type of primitive reflex that is elicited by lightly touching or tapping on the lips with an object such as a tongue blade, reflex hammer, or the examiner's finger. At times the reflex is obtained merely by approaching the lips with an object. A positive suck reflex consists of sucking movements by the lips when they are stroked or touched.

Changes in these genes cause rare conditions in which Suck reflex 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 |
|---|---|---|
| NGLY1N-glycanase 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.
