ABSTRACT
Abstract Objective:
To determine the effect type I collagen gene polymorphism alpha-2 (COL1A2) (rs42524) on the formation of scar tissue that is localized in the head and neck areas. Material andMethods:
Sixty patients with scars in different areas of the head and neck were examined. The patients were divided into four subgroups, according to the types of scarring G I 15 patients with normotrophic scars; G ІІ 15 patients with atrophic scars; G ІІІ 15 patients with hypertrophic scars; and G IV 15 patients with keloid scars. The age of patients ranged from 17 to 54 years. The single-nucleotide polymorphic site of the COL1A2 (rs42524) gene was detected by a polymerase chain reaction and subsequent analysis of restriction fragment lengths. Pearson's chi-squared test with Yates's correction and Fischer's exact test were used.Results:
There were no significant changes between the control and basic groups (p=0.83) at analyzing the frequencies of G and C alleles. For the G allele, the calculation of odds ratio between the basic and control groups was 0.93 at 95% confidence interval (CI) (0.50-1.75), for the C allele - OR was 1.07 at 95% CI (0.57-2.01).Conclusion:
Our studies may indirectly indicate the activation of the skin's protective reaction to physiological scarring and dosed scar formation in different areas of the head and neck.Palavras-chave
