Özet

Background: Holoprosencephaly (HPE), the most common malformation of the brain, results from failed or incomplete separation of the embryonic forebrain (prosencephalon). HPE occurs in approximately 1 in 250 embryos and in about 1 in 10,000 births. It is etiologically heterogeneous, and may be caused by cytogenetic anomalies and teratogenic influences; it occurs as part of a syndrome, or due to heterozygous mutations in 1 of over 10 HPE-associated genes. ZIC2 mutations are the second-most common cause of non-syndromic non-chromosomal HPE (after sonic hedgehog) and occur de novo in 74% of the affected probands.
