CYP2D6*4

Distribution of HLA-B27 and CYP2D6*4 mutations in the middle Black Sea area (Tokat) of Turkey

S. Sahin, Aydogan, L., Benli, I., and Ozyurt, H., Distribution of HLA-B27 and CYP2D6*4 mutations in the middle Black Sea area (Tokat) of Turkey, vol. 10, pp. 3987-3991, 2011.

We analyzed distribution of HLA-B27 and CYP2D6*4 mutations in 249 patients from Tokat province in Turkey with symptoms of arthritis, sacroiliac, joint and back pain, using a LightCycler 480 II Real-Time PCR thermal cycler. The Genes-4U was applied for studying HLA-B27 mutation, and the Tib-Molbiol commercial kit was used to examine the CYP2D6*4 mutation. Among the 249 patients, 18.5% had the HLA-B27 mutation. The CYP2D6*4 mutation was found in 22.0% (six homozygotes). Ten patients had both mutations. These frequencies are similar to what has been reported from other populations.
