Trait
Prenatal double bubble sign
Sonographic detection of a double bubble sign in the upper abdomen is strongly indicative of duodenal obstruction. One bubble represents fetal stomach, and the other is attributed to a dilated proximal part of the duodenum; continuity between both bubbles is required for the sign.
Summary
- Body system
- Abnormality of prenatal development or birth

Changes in these genes cause rare conditions in which Prenatal double bubble sign 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 |
|---|---|---|
| FBXO22F-box protein 22 | Sometimes (5–29%) | 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.
