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.
Our results indicate that VEGF (rs2010963) polymorphism and CTC haplotype of the VEGF SNPs (rs699947, rs833061, and rs2010963) confer an increased risk of psoriasis in the South Indian Tamil population.
The aim of this meta-analysis was to investigate large-scale evidence to determine the degree to which four common VEGF polymorphisms (+405C>G [dbSNP: rs2010963], -460T>C [dbSNP: rs833061], -2578C>A [dbSNP: rs699947], and -1154G>A [dbSNP: rs1570360]) are associated with susceptibility to psoriasis.
