Autosomal recessive congenital ichthyosis due to novel CYP4F22 mutation presenting with a collodion membrane and ocular manifestations

Abstract

Autosomal recessive congenital ichthyoses (ARCI) are a range of genetic disorders of keratinization. The rare CYP4F22 gene mutation can present with or without collodion membrane at birth and leads to the development of mild ichthyosis phenotype. We report a case of a novel pathogenic CYP4F22 genetic mutation presenting with collodion membrane and ocular manifestations. Ocular manifestations have recently been reported in a patient with ARCI with known CYP4F22 mutation, which further supports a possible correlation between the CYP4F22 mutation and this distinct phenotype.

Keywords: CYP4F22; autosomal recessive congenital ichthyosis; collodion membrane; ophthalmology.
