dc.description.abstractThe autosomal recessive disorder, hereditary tyrosinemia type 1 (HT1), is caused by a defective fumarylacetoacetate hydrolase enzyme. Consequently intermediate metabolites such as fumarylacetoacetate, succinylacetone and p-hydroxyphenylpyruvic acid accumulate. Characteristic to HT1 is the development of hepatocellular carcinoma, irrespective of dietary intervention or pharmacological treatment. Carcinogenesis may occur through a chromosomal instability mutator phenotype or a microsatellite instability phenotype, and deficient DNA repair may be a contributing factor thereof. The purpose of this study was to investigate the expression of DNA repair proteins, and the possible occurrence of microsatellite instability in HT1. Gene expression analyses show low expression of hOGG1 and ERCC1 in HT1 patient lymphocytes. Results from microsatellite instability analyses show allelic imbalance on chromosome 7 of the fah−/− mouse genome, and instability of the D2S123, D5S346 and (possibly) D17S250 microsatellite markers, in HT1 patient lymphocytes.en_US
