IL-6 and DRD2 Genesare Associated with Hyperkinetic Disorder
Geny pro IL-6 a DRD2 souvisejís hyperkinetickou poruchou
Souhrn:
Vztah mezi TaqI A polymorfi smem genu pro dopaminový receptor D2 (DRD2) a ADHD,alkoholismem a drogovou závislostí byl již dříve publikován. Polymorfi smus -174 genu prointerleukin-6 (IL-6) se podílí na vzniku alkoholismu. V naší asociační studii jsme studovali rozdílmezi alelickými a genotypovými frekvencemi shora uvedených polymorfi smů mezi chlapci trpícímiADHD a chlapci v kontrolní skupině. Bukální tkáň posloužila pro izolaci genomové DNA za využitíkomerčně dostupného kitu UltraClean Tissue DNA (MoBio, USA). PCR s následnou restrikčníanalýzou byla použita pro určení genotypů. Genotypové a alelické frekvence TaqI A polymorfi smugenu pro DRD2 se statisticky lišily mezi skupinou chlapců s ADHD a kontrolní skupinou (p < 0,04a p < 0,002), jakožto i genotypové a alelické frekvence polymorfi smu -174 genu pro IL-6 byly statistickyvýznamně odlišné mezi studovanými skupinami chlapců (p < 0,004 a p < 0,001). Naše studie potvrdiladříve objevený vztah mezi TaqI A polymorfi smem genu pro DRD2 a ADHD a přinesla nové výsledky- poprvé objevený vztah mezi polymorfi smem -174 genu pro IL-6 a ADHD.

Overview
TaqI A polymorphism of the dopamine receptor D2 gene (DRD2) was previously associated withADHD, alcoholism, drug dependence etc., while -174 polymorphism of interleukin-6 (IL-6) gene wasassociated with alcoholism. In our association study, we studied the difference in genotype andallelic frequencies of the above mentioned polymorphisms between boys with ADHD and boys incontrol group. Buccal tissue was used for isolation of genomic DNA using commercial kit UltraCleanTissue DNA (MoBio, USA). PCR with subsequent restriction analysis was used for determination ofgenotypes. Genotype and allelic frequency of TaqI A polymorphism of DRD2 gene was statisticallydifferent between ADHD group and control group (P < 0.04 and P < 0.002, respectively), as well asgenotype and allelic frequency of -174 polymorphism of IL-6 was statistically different betweenstudied groups of boys (P < 0.004 and P < 0.001, respectively). Our study confi rmed the associationfound previously between TaqI A polymorphism and ADHD and provided new data about the fi rstdiscovered association between -174 polymorphism of IL-6 gene and ADHD.
Key words:
ADHD, IL-6, DRD2, association study, polymorphism.
