▶Association of TGFβ1 and clinical factors with scar outcome following melanoma excisionAssociationN=202Ward SV et al.(2012)· Archives of Dermatological Research
Genetic association study of 202 melanoma patients examining SNPs in 24 candidate genes related to pigmentation and wound healing in relation to scar outcome. SNP rs8110090 in TGFβ1 was significantly associated with poorer scar outcomes (p=0.0002). Clinical factors including younger age, shorter time since surgery, and presence of infection or eczema were also associated with worse scarring.
About MC1R
This intronless gene encodes the receptor protein for melanocyte-stimulating hormone (MSH). The encoded protein, a seven pass transmembrane G protein coupled receptor, controls melanogenesis. Two types of melanin exist: red pheomelanin and black eumelanin. Gene mutations that lead to a loss in function are associated with increased pheomelanin production, which leads to lighter skin and hair color. Eumelanin is photoprotective but pheomelanin may contribute to UV-induced skin damage by generating free radicals upon UV radiation. Binding of MSH to its receptor activates the receptor and stimulates eumelanin synthesis. This receptor is a major determining factor in sun sensitivity and is a genetic risk factor for melanoma and non-melanoma skin cancer. Over 30 variant alleles have been identified which correlate with skin and hair color, providing evidence that this gene is an important component in determining normal human pigment variation.
