Genes affected

SYDE1 (HGNC:25824): (synapse defective Rho GTPase homolog 1) The protein encoded by this gene is a Rho GTPase-activating protein highly expressed in placenta. The encoded protein is involved in cytoskeletal remodeling and trophoblast cell migration. Decreased expression of this gene has been associated with intrauterine growth restriction (IUGR).
