Researchers believe that the disorder results from some kind of disturbance in the fetal environment that occurs between the second and sixth months of pregnancy. The underlying causes of colpocephaly are multiple and diverse. Causes include chromosomal anomalies such as trisomy-8 mosaicism and trisomy-9 mosaicism; intrauterine infection such as toxoplasmosis; perinatal anoxic-ischemic encephalopathy; and maternal drug ingestion during early pregnancy, such as corticosteroids, salbutamol, and theophylline. In addition, a familial occurrence of colpocephaly has been noted in three reports. A genetic origin with an autosomal recessive or X-linked recessive inheritance was suggested in these familial cases.
