Genome-wide association studies have found the single nucleotide polymorphism (SNP) c.C2458T, at the caspase recruitment domain family member 14 (CARD14) gene, to be associated with psoriasis.
A DNA variant, rs734232, altering a RUNX1 binding site was recently reported as susceptibility allele at PSORS2 (17q25) in cohorts of psoriasis patients from the US.
It is known that particular caspase recruitment domain family member 14 (CARD14) gene mutations are associated with familial PRP and certain forms of psoriasis.
Single-nucleotide polymorphisms and haplotypes in the VEGF receptor 3 gene and the haplotype GC in the VEGFA gene are associated with psoriasis in Koreans.
In the current study, we assessed IL-37 in two well-known psoriasis models: a human keratinocyte cell line (HaCaT) and the keratin 14 VEGF-A-transgenic mouse model.
This meta-analysis suggests the VEGF+405 C/G polymorphism confers susceptibility to psoriasis in Asians, and that the -460 C/T and -1154 A/G polymorphisms confer susceptibility to psoriasis in Europeans.
Haplotype analysis suggests that the coexistence of the polymorphisms rs1799964 (TNF-α), rs2010963 (VEGF), rs833061 (VEGF), and rs6311 (5HT2A) may be a protective factor for psoriasis.
The allele of rs2237051 G increased the erythema during the treatment, and no polymorphism of VEGF and EGF gene was found to be associated with the susceptibility and efficacy in psoriasis.
Results from the meta-analysis do support the hypothesis that single-nucleotide polymorphism markers at +405C>G, -460C>T, and -1154G>A of the VEGF gene may serve as biological markers of psoriasis.
Evidence for an association between EBV-negative cHL and rs20541 (5q31, IL13: OR = 1.53, 95% CI = 1.32 to 1.76, P = 5.4 x 10(-9)), a variant previously linked to psoriasis and asthma, was observed; however, the evidence for replication was less clear.
A multitiered genetic association study of 25 215 single-nucleotide polymorphisms (SNPs) in three case-control sample sets (1446 patients and 1432 controls) identified three IL13-linked SNPs (rs1800925, rs20541 and rs848) associated with psoriasis.
Notably, one additional psoriasis-associated variant, rs27524 (5q15, ERAP1), showed evidence of an association with cHL in the genome-wide association study (OR = 1.21, 95% CI = 1.10 to 1.33, P = 1.5 × 10(-4)) and replication series (P = .03).
