Cytokine Gene Polymorphisms in Saudi Patients With Atopic Dermatitis: A Case-Control Study.

The cause of atopic dermatitis (AD) is multifactorial and a number of genes including cytokines have been involved. We genotyped 315 subjects for polymorphisms in and and genes. Patients had significantly higher frequency of GA genotype of TNF-α (-308 G/A) than healthy controls.

The Protein Tyrosine Phosphatase Nonreceptor 22 () R620W Functional Polymorphism in Psoriasis.

Background: Psoriasis is a complex autoimmune disease caused by the interaction of genetic and environmental factors. gene polymorphism has been reported to affect psoriasis susceptibility; however, no data are available for Middle Eastern populations.

Objective: The aim of this study was to investigate the association of PTPN22 (1858C/T) R620W polymorphism with psoriasis in a Saudi cohort.

Apolipoprotein E gene polymorphism and serum lipid profile in Saudi patients with psoriasis.

Background/aim: Apolipoprotein E (APOE) gene variants have been reported to influence psoriasis risk. However, data is limited to a few ethnicities and no similar study has been performed in middle eastern populations. We investigated this association in Saudi psoriasis patients.
