Background/Aim. Wilson disease (WD) is a life threatening autosomal recessive genetic disorder with impaired cooper metabolism and associated with hepatic, neurological and psychiatric symptoms. The aim of our study was to investigate the prevalence of the ATP7B gene mutation in patients with hepatic presentation of WD in Lithuania. Methods. Twenty two unrelated Lithuanian families, including 27 WD patients were tested. Clinically WD diagnosis was established in accordance to the Leipzig scoring system. Genomic DNA was extracted from whole venous blood using a salt precipitation method. Firstly, the semi-nested polymerase chain reaction (PCR) technique was used to detect the c.3207C>A (p.H1069Q) mutation. Patients not homozygous for the c.3207C>A (p.H1069Q) mutation were further analysed. Results. Total of 27 WD patients presented with hepatic disorders and 20 their degree relatives (including 16 siblings) were studied. [...].
