Backgroun.: Parkin.on.s disease (PD) is caused by complex in.eraction. between.gen.tic an. en.iron.en.al factors. Men.elian.forms of PD rarely occur in.practice, but respective gen.s may play some role in.pathogen.sis of a common.sporadic form of the disease. Methods: We an.lyzed most frequen. kn.wn.poin. mutation. (PMs) an. sin.le-n.cleotide polymorphisms (Sn.s) in.gen.s respon.ible for mon.gen.c PD in.408 Russian.patien.s, usin. arrayed primer exten.ion.(APEX), real-time PCR, an. restriction.fragmen. len.th polymorphism an.lysis. Results: We detected on.y three heterozygous PMs in.the PARK2 gen. in.three n.n.related patien.s with early-on.et sporadic PD. n. association.between.PD an. the studied Sn.s was iden.ified. Con.lusion. The examin.d PMs an. Sn.s in.gen.s respon.ible for mon.gen.c PD do n.t con.ribute sign.fican.ly to the developmen. of sporadic PD in.Russia.
