title: The association of arylendosulfatase 1 (SULF1) gene polymorphism with recurrent miscarriage.
abstract: OBJECTIVE
  One of the most common problems in reproductive medicine is recurrent miscarriage (RM). There is increasing evidence showing genetic susceptibility of women is an important risk factor in the occurrence of RM. In recent years, there is a growing interest in sulfate and its role in fetal development. A novel mechanism of SULF1 has been demonstrated for modifying the activities of some growth factors and signalling molecules that have major roles during embryogenesis. The aim of present study was to evaluate the association of SULF1 gene polymorphism (rs6990375 G > A) in Iranian patients with RM.
  
  
  METHODS
  We established a case-control study of 200 Iranian women: 100 patients with the history of two or more RM as cases and 100 healthy women with at least two cases of successful pregnancy and no history of miscarriage as controls. The polymorphism was examined by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method.
  
  
  RESULTS
  The genotypic analysis between case and controls showed significant differences (p-value = 0.000). Allelic analysis showed no significant correlation (Χ2 = 3.36, p-value = 0.066). The heterozygous genetic variant was significantly higher among healthy women (OR = 12.67, 95% CI = 6.47-24.79).
  
  
  CONCLUSIONS
  Our data showed that rs6990375 polymorphism of SULF1 gene could be among one of the factors related to RM in Iranian women. Further evaluation of this polymorphism may be important and need further studies.
