Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to identify the gene or genes responsible for keloid formation. Keloids are raised scars on the skin that form after a minor injury. A tendency to develop keloids often runs in families, suggesting a possible genetic basis. People who have had a classic (butterfly-shaped or wound-overflowing) keloid for at least one year may be eligible for this study. In addition to these probands (original participants), family members over 12 years of age who have either classic or non-classic keloids and those 18 years of age or older without keloids may participate. Probands and family members with keloids will have a medical history focusing on skin problems-particularly keloids-and a skin examination. In some cases, with the subject s permission, photos of the keloids will be taken. All participants will have 35 milliliters (about 2 tablespoons) of blood drawn for DNA (genetic) testing and for measurement of blood proteins, including cytokines, which can affect other tissues and cause scarring. Part of the blood sample will be used for additional genetic studies unrelated to keloids. The samples will be coded for confidentiality.
