Collagen type III and elastin genes polymorphism and the risk of nonsyndromic striae.

In conclusion, we found that there are some clinical factors that reduced the risk of SD: history of intended weight loss, negative family history of SD, and lower BMI. Gene polymorphisms analysis in patients with SD may help to establish the etiology of these lesions and to target the therapy. Analysis of polymorphisms of elastin gene (rs7787362) did not show differences in allele distribution between women with and without SD. Polymorphisms of COL3A1 gene (rs1800255) also did not differ between the examined groups.
