De Novo Interstitial Deletion of 3q22.3-q25.2 Encompassing FOXL2, ATR, ZIC1, and ZIC4 in a Patient With Blepharophimosis/Ptosis/Epicanthus Inversus Syndrome, Dandy-Walker Malformation, and Global Developmental Delay

Abstract

We report a case carrying a de novo interstitial deletion of chromosome 3q22-q25. The clinical phenotype of this case included blepharophimosis/ptosis/epicanthus inversus syndrome, Dandy-Walker malformation, and global developmental delay. Contiguous heterozygous deletion of FOXL2, ATR, ZIC1, and ZIC4 was postulated as the causative mechanism of the clinical phenotype. The association of blepharophimosis, ptosis, and epicanthus inversus syndrome with developmental delay or mental retardation may be an indication for the use of brain imaging and chromosomal analysis capable of detecting chromosomal rearrangements encompassing several candidate genes.
