2 genes linked to Impaired convergence

Changes in these genes cause rare conditions in which Impaired convergence 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
RNU2-2RNA, U2 small nuclear 2	Always	In 1 condition
SALL4spalt like transcription factor 4	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.
