Psoriasis is a complex disease with multifactorial mode of inheritance,whichmeans that its clinicalmanifestations depend uponmultiple genesinteracting with environmental agents. The major genetic factor responsiblefor 35-50% susceptibility for early psoriasis in the Caucasian population,HLA-Cw*06, is located within the major histocompatibility complex(MHC) on the sixth chromosome. Whole genome associationstudies, the newest research trend, revealed three genetic, non-MHCrelated pathways connected with psoriasis susceptibility: Th17, Th2 andNF-κB-dependent. These genes are responsible for inflammation, epidermalproliferation and epidermal barrier function in psoriasis.
