Clinical Description OMIM Holoprosencephaly (HPE; see 236100) is the most common structural anomaly of the human brain and is one of the anomalies seen in patients with deletions and duplications of chromosome 13. On the basis of molecular analysis of a ...
Genotype-Phenotype Correlations OMIM Among 34 patients with holoprosencephaly, Dubourg et al. (2004) observed that mutation in ZIC2 was associated with anencephaly.

Mercier et al. (2011) reported the clinical and molecular features of a large European series of 645 HPE ...

Molecular genetics OMIM Brown et al. (1998) reported that heterozygous mutations in the human ZIC2 gene, a homolog of the Drosophila 'odd-paired' (opa) gene, are associated with HPE. Haploinsufficiency of ZIC2 is likely to cause the brain malformation seen in 13q ...
Population genetics OMIM In a targeted screening study of 4 genes in 86 Dutch patients with holoprosencephaly, Paulussen et al. (2010) found that 21 (24%) had heterozygous mutations in 1 of 3 of the genes. Three (3.5%) had mutations in the ...
