15 genes linked to Uneven or disproportionate growth of one body part compared to another

Changes in these genes cause rare conditions in which Uneven or disproportionate growth of one body part compared to another 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
AKT1AKT serine/threonine kinase 1	Very often (80–99%)	In 1 condition
H19H19 imprinted maternally expressed transcript	Very often (80–99%)	In 1 condition
HRASHRas proto-oncogene, GTPase	Very often (80–99%)	In 1 condition
IGF2insulin like growth factor 2	Very often (80–99%)	In 2 conditions
KRASKRas proto-oncogene, GTPase	Very often (80–99%)	In 1 condition
NRASNRAS proto-oncogene, GTPase	Very often (80–99%)	In 1 condition
PIK3CAphosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha	Very often (80–99%)	In 3 conditions
GRB10growth factor receptor bound protein 10	Often (30–79%)	In 1 condition
ARL6IP6ARF like GTPase 6 interacting protein 6	Sometimes (5–29%)	In 1 condition
CDKN1Ccyclin dependent kinase inhibitor 1C	Sometimes (5–29%)	In 1 condition

HMGA2high mobility group AT-hook 2	Sometimes (5–29%)	In 1 condition
PLAG1PLAG1 zinc finger	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.
