Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) associated with interstitial deletion of band 3q22: review and gene assignment to the interface of band 3q22.3 and 3q23.

We report on a child with blepharophimosis, ptosis, and epicanthus inversus (BPES), developmental delay and an interstitial deletion of band q22 of chromosome 3. A review of chromosome 3q anomalies associated with eye abnormalities, specifically blepharophimosis and ptosis, strongly suggests that a locus for eyelid development is present at the interface of bands 3q22.3 and 3q23.
