Abstract

Objective: Holoprosencephaly (HPE, #MIM 236100) is the most common developmental defect of midline cleavage in the human forebrain. Environmental, genetic, and multifactorial causes are involved in its etiology. About half of the cases have chromosome aberrations such as trisomies 13 and 18, triploidy and structural imbalances. Single gene mutations have been shown in similar to 25% of cases. In this retrospective study, we aimed to determine the etiological factors related to HPE in 127 fetuses.
