Entire blood 875320-29-9 chemical information samples were collected from 360 individuals with CVD from St.Thomas Hospital, Kerala, India. CVD resulting from obstructions for instance neoplasm had been excluded from the study. Differential diagnosis was performed by an skilled vascular surgeon and presence of distichiasis was ruled out by an ophthalmologist. Individuals with kind 2 diabetes mellitus have been also excluded since genetic variants of FoxC2 have been reported to outcome in susceptibility to diabetes mellitus. Blood samples were collected from age and gender matched 352 healthy controls with no known family members history for CVD. For tissue level expression analysis, varicose vein tissue samples were collected from 22 sufferers admitted for treatment of CVD by operative therapies at Kempegowda Institute of Healthcare Sciences, Bangalore, India. Saphenous control vein samples from 20 patients who underwent coronary artery bypass graft surgery at Sri Jayadeva Institute for Cardiovascular Sciences & Research, Bangalore, India have been also collected for the study. Whole blood samples had been also collected from these 22 individuals and 20 controls for sequencing assays. Relevant data regarding the clinical characteristics of individuals were collected from healthcare records of the hospitals participating in the study.

Loved ones history, occupational and lifestyle data have been collected to examine their influence in aggravating disease manifestation. Disease phenotypes were categorized according to CEAP classification system. Varicose veins without odema or pigmentation had been classified under C2. Only two.9% of all our sufferers have been in CEAP Class 3 in which varicose vein with oedema alone are found. The individuals in this study were mostly from CEAP Class 4, 5 and 6 who presented various clinical signs which include pigmentation, ulceration along with oedema due to CVD.
