Introduction

Julie V. Schaffer* Mosaicism and Linear Lesions 62

Key features

ย„Mosaicism for genes expressed in the skin presents as a patchy distribution of affected and unaffected skin

ย„The classical pattern follows the lines of Blaschko but varies according to cell type and timing of mosaicism

ย„Epidermal nevi represent mosaicism for a variety of genes with variable associated features

ย„Some mosaic disorders are recognizable as segmental forms of autosomal dominant skin disorders

ย„If there is also gonadal mosaicism, offspring may have the

ยญcorresponding generalized condition
