Trait

Beevor's sign

Weakness of the inferior portion of the rectus abdominal muscle, which is ascertained clinically as follows. When a patient sits up or raises the head from a recumbent position, the umbilicus is displaced toward the head. This is the result of paralysis of the inferior portion of the rectus abdominal muscle, so that the upper fibers predominate pulling upwards the umbilicus.

5 genes linked to Beevor's sign

Changes in these genes cause rare conditions in which Beevor's 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.

GeneHow often it is seenConditions
DNMT3BDNA methyltransferase 3 betaOften (30–79%)In 1 condition
DUX4double homeobox 4Often (30–79%)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.
