This study was undertaken to correlate plasma vWF levels with plasma cortisol and single nucleotide polymorphisms (SNPs) at positions -2659 and -2525 in Cushing syndrome patients in India.
This is not a constant feature of CS, however; it depends on particular single nucleotide polymorphism (SNP) haplotypes in the VWF gene promoter: haplotype 1 (-3268G/-2709C/-2661A/-2527G) confers a greater risk of VWF upregulation by cortisol than haplotype 2 (-3268C/ -2709T/-2661G/-2527A).
Microsatellite (GT)(n) is part of the von Willebrand factor (VWF) promoter region that influences the glucocorticoid-induced increase in VWF in Cushing's syndrome.
Polymorphisms in von Willebrand factor gene promoter influence the glucocorticoid-induced increase in von Willebrand factor: the lesson learned from Cushing syndrome.
