Abstract:
PURPOSE: To report the first case of steroid sulfatase (STS) gene deletion, confirmed by multiplex ligation-dependent probe amplification (MLPA) analysis in identical twins with pre-Descemet corneal dystrophy associated with X-linked ichthyosis. CASE SUMMARY: 19-year old identical twin brothers with itching senses and hereditary thick scaly skin of the extremity and trunk visited our dermatologic clinic. Upon visiting, an ophthalmologic consultation with anterior segment examination showed diffuse punctate corneal opacities in the pre-Descemet layer. On MLPA analysis of the identical twin brothers, a definitive diagnosis of X-linked ichthyosis was made by identifying STS gene deletion. CONCLUSIONS: Identification of the deletion and mutation of the involved gene using gene analysis can provide insight to diagnosis and clinical characteristics of X-linked ichthyosis.
