Objectives of Research:
Keloid disease (KD) is one of the most aggressive forms of abnormal skin scarring in humans. Most forms of KD cause hugely disfiguring and symptomatic lesions in affected individuals with little hope of successful treatment as it is highly recurrent. The sufferers of KD face serious aesthetic, physical, psychological and social consequences that may culminate in substantial emotional and financial costs. Keloids comprise a diverse group of unsightly prominent scars that are persistent and chronically active. Keloid scars tend to recur following surgical excision and other treatment modalities making them a difficult medical challenge and a frustrating ailment for sufferers.
The rate of occurrence of keloid disease is reported to be higher in the Black population. The increased familial clustering in keloid disease, its increased prevalence in certain races and in identical twins suggests a strong genetic predisposition to keloid formation. Understanding the genetic basis of keloid disease may provide future prognostic and diagnostic advice to patients and help to develop novel therapeutic regimes for treatment of skin fibrosis.
The objective of this study is to recruit patients with familial keloids and other affected and unaffected family members. This will allow us to determine the inheritance mode and to conduct genetic studies (linkage analysis). The genetic linkage analysis will help identify sequences on the human genome that may be responsible for keloid scarring. The potential benefits of identifying the sequences will be of great scientific and clinical importance. |
