摘　　要：AIM： To investigate the prevalence of the ATP7B gene mutation in patients with hepatic presentation of Wilson＇s disease （WD） in Lithuania. METHODS： Eleven unrelated Lithuanian families, including 13 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 analyzed. The 21 exons of the WD gene were amplified in a thermal cycler （Biometra T3 Thermocycler, G0ttingen, Germany）. Direct sequencing of the amplified PCR products was performed by cycle sequencing using fluorescent dye terminators in an automatic sequencer （Applied Biosystems, Darmstadt, Germany）. RESULTS： Total of 13 WD patients （mean age 26.4 years; range 17-40; male/female 3/10） presented with hepatic disorders and 16 their first degree relatives （including 12 siblings） were studied. Some of WD patients, in addition to hepatic symptoms, have had extrahepatic disorders （hemolytic anemia 3; Fanconi syndrome 1; neurophsychiatric and behavioural disorder 2）. Liver biopsy specimens were available in all of 13 WD patients （8 had cirrhosis; 1-chronic hepatitis; 3-acute liver failure, 1-1iver steatosis）. Twelve of 13 （92.3%） WD patients had the c.3207C〉A （p.HI069Q） mutation, 6 of them in both chromosomes, 6 were presented as compound heterozygotes with additional c.3472-82delGGTTTAACCAT, c.3402delC, c.3121C〉T （p.RI041W） or unknown mutations. For one patient with liver cirrhosis and psychiatric disorder （Leipzig score 6）, no mutations were found. Out of 16 first degree WD relatives, 11 （68.7%） were heterozygous for the c.3207C〉A （p.H1069Q） mutation.
