The neuronal theory of the pathogenesis of vitiligo is supported by clinical, ultrastructural and biochemical findings. Cyclin-dependent kinase 5 regulatory subunit associated protein 1 (CDK5RAP1) is expressed in neuronal tissues, and cyclin-dependent kinase 5 (CDK5) seems to be critically involved in the migration of neuroblasts during early post-natal development. To evaluate whether CDK5RAP1 polymorphisms are associated with vitiligo patients in the Korean population, we conducted a case-control association study of 296 vitiligo patients and 426 healthy controls. A total of two single nucleotide polymorphisms (SNPs) of CDK5RAP1 were investigated. Genotypes were determined by polymerase chain reaction (PCR) and direct sequencing. A synonoymous SNP (rs291700, Thr54Thr) and intron SNP (rs158676) of CDK5RAP1 were associated with onset age of the vitiligo (rs291700, p=0.040 in co-dominant 1 and p=0.036 in overdominant; rs158676, p=0.034 in overdominant). Haplotype (AC) showed a difference between the vitiligo and control groups (p=0.036).
These results suggest that CDK5RAP1 may be a risk factor of vitiligo in the Korean population.
