Aim of study: To investigate the prevalence of ATP7B gene mutation of patients with hepatic presentation of Wilson's disease (WD) in Lithuania. Methods: Twelve unrelated Lithuanian families, including 15 WD patients were tested. Clinical WD diagnosis was established in accordance to leipzig scoring system. Genomic DNA was extracted from whole venous blood using a salt precipitation method. Firstly, semi-nested PCR technique was used to detect the c.3207C>A (p.H1069Q) mutation. Patients not homozygous for c.3207C>A (p.H1069Q) mutation were further analyzed. The 21 exons of the WD gene were amplified in a thermal cycler (Biometra T3 Thermocycler, Göttingen, Germany). Direct sequencing of the amplified PCR products was performed by cycle sequencing using fluorescent dye terminators in an automatic sequencer (Applied Biosystems, Dramstadt, Germany). [...]
