Differential susceptible loci expression in keloid and hypertrophic scars in the Chinese Han population.

Abstract

Hypertrophic scars (HSs) and keloids (KDs) are commonly seen as 2 different diseases. We aimed to find potential genes associated with KD and HS formation. We selected 4 single-nucleotide polymorphisms (SNPs) (based on the whole genome resequencing we have done) for replication in 71 KDs and 50 HSs using the Sequenom Massarray system. We found evidence of significant association at rs181924090, P = 0.0075; rs183178644, P = 0.0151; and rs151091483, P = 0.0073. However, at rs141156594, there was no significant association between KD and HS (P = 0.7893). rs181924090 (11p15.5, SIRT3), rs151091483 (17p13.1, MYH8), and rs183178644 (6p25.3, HUS1B) are new potential SNPs associated with KD formation, especially closely related to tumor behaviors as KD is, whereas rs141156594 (18q22.2, RTTN) is a new SNP involved in the extracellular matrix formation in wound healing.
