Pre-Descemet corneal dystrophy and X-linked ichthyosis associated with deletion of Xp22.31 containing the STS gene.

ABSTRACT:

Purpose

To report the association of X-linked ichthyosis and pre-Descemet corneal dystrophy with a deletion of the steroid sulfatase gene (STS) detected with microarray-based comparative genomic hybridization (aCGH).

Methods

A slit-lamp biomicroscopic examination and cutaneous examination were performed, after which a saliva sample was collected as a source of genomic DNA. Polymerase chain reaction amplification of each of the 10 exons of STS was performed, as was aCGH on genomic DNA to detect copy number variation.

Results

The slit-lamp examination revealed punctate opacities in the posterior corneal stroma of each eye. The cutaneous examination demonstrated scaling and flaking skin of the arms and legs. Polymerase chain reaction amplification using primers designed
