Relationship between Serotonin-2A Receptor Gene Polymorphism and Wound Healing in Brazilian Patients

Abstract Genetic changes in platelet serotonin receptors (5-HTR2A) impair the initial process of tissue repair, regardless of the triggering factor of the skin wound. Objective was to determine the prevalence of the 102T-C polymorphism in the 5-HTR2A gene in Brazilian patients with and without skin wounds. Cross-sectional case-control study, in which 100 patients were evaluated as Cases Group (subdivided into I-with Chronic Wound and II-with Acute Wound) and 100 individuals as Controls, of both genders. DNA was extracted from leukocytes of peripheral blood and the region that covers the polymorphism was amplified by the molecular techniques Polymerase Chain Reaction/Restriction Fragment Length Polymorphism. The TT genotype was significantly associated with the protective factor against alterations in the healing process of skin wounds (OR: 0.4833; 95%CI: 0.2704-0.8638; p
