Official title
Genotypic and Phenotypic Analysis of Adolescents With Heavy Menstrual Bleeding and Low Von Willebrand Activity
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a research study for patients diagnosed with heavy menstrual bleeding (HMB) and low Von Willebrand Factor (VWF). Menstruation, also known as a period, is the regular discharge of blood and tissues from the uterus. HMB is having a heavier amount of discharge during menstrual period. Low Von Willebrand Factor means that the participant has lower level of a blood protein that is important for clotting of blood and so, the participant is at a higher risk for bleeding. The purpose of this project is to study the genetic differences of adolescent females with HMB and low VWF activity and compare the genetic differences with their bleeding manifestations, response to medications and outcome.
