To evaluate PTPN22 C1858T polymorphism and the risk of endometriosis. A meta-analysis of 10 published case-control studies (from four articles), with a total sample of 971 cases and 1,181 controls, was performed. We estimated risk (odds ratio and 95% confidence intervals) of endometriosis associations with the C1858T polymorphism. A significant increased risk in all genetic models of the variant T allele with endometriosis (odds ratio: 3.14-5.55; p<0.00001-0.002) was found. The analysis without the study whose controls deviated from the Hardy-Weinberg equilibrium exacerbated these effects in the homozygous and recessive models (odds ratio: 7.19-9.45; p<0.00001-0.0002). In the Italian subgroup, a significant risk association was found in the homozygous and recessive models (odds ratio: 8.72-11.12; p=0.002). The associations observed between PTPN22 (C1858T) and the risk of endometriosis suggest this polymorphism might be a useful susceptibility marker for this disease. Avaliar o polimorfismo PTPN22 C1858T e o risco de endometriose. Foi realizada uma metanálise de 10 estudos caso-controle publicados (a partir de quatro artigos), com uma amostra total de 971 casos e 1.181 controles. O risco da associação da endometriose com o polimorfismo C1858T foi estimado em razão de chance e intervalo de confiança de 95%. Observou-se um aumento de risco significativo em todos os modelos genéticos com o alelo variante T e a endometriose (razão de chance: 3,14-5,55; p<0,00001-0,002). A análise sem incluir o estudo, em que os controles não estavam em equilíbrio de Hardy-Weinberg, mostrou aumento significativo nos modelos homozigotos e recessivos (razão de chance: 7,19-9,45; p<0,00001-0,0002). No subgrupo italiano, uma associação significativa foi encontrada considerando os modelos homozigoto e recessivo (razão de chance: 8,72-11,12; p=0,002). As associações observadas entre PTPN22 (C1858T) e o risco de endometriose sugerem que este polimorfismo pode ser um marcador de suscetibilidade para a endometriose.
