CDKN2A and psoriasis: ANRIL (antisense non-coding RNA in the INK4 locus) was identified as a risk locus for psoriasis after the genotyping of four single-nucleotide polymorphisms (SNPs) in this lncRNA; specific haplotypes were more prevalent among psoriasis cases (lesional tissue samples form patients with psoriasis and age-/sex-matched controls enrolled in the study), with the recognition of allelic variants possessing protective roles and even genetic variables associated with the risk of cardiovascular disease [36].
