Adv Exp Med Biol. 2022;1367:119-135. doi: 10.1007/978-3-030-92616-8_5.

Abstract

Lichen planus (LP) is a multifaceted autoimmune disease affecting the skin, nails, hair, and mucous membranes, with several clinical subgroups. Cell-mediated immunity plays a key role in its progression. This chapter reviews the known genetic associations of lichen planus including HLA as well as non-HLA genes.
