This new connection suggests that genes in Caucasians and this specific Chinese population may be involved in the origin and development of psoriasis. As the first meta-analysis performed in the area of this disease, the data collected confirms previous studies and spotlights two regions on chromosomes 6 (major histocompatibility complex – MHC) and 4. Conclusively, the 4q28-q31 region has been identified as a focus for future investigation.
Over the past few years, ten genome-wide scans have been conducted, classifying 19 candidate regions for psoriasis. Of these regions, locus PSORS1 (within the MHC) has shown a large presence in the study results, encompassing data from six of the ten scans previously mentioned.
