    Missense mutations within RING finger domain of BRCA1 gene detected in high risk Czech patients with hereditary breast and ovarian cancer

  • Original language description

    Germline mutations in highly penetrant cancer susceptibility gene BRCA1 cause genetic predisposition to breast and ovarian cancers. Mutations generating a premature stop codon are considered to be pathogenic. However, distinguishing disease-causing missense mutations from rare polymorphisms remains problematic. Three different missense mutations located within conserved C3HC4 RING finger domain of BRCA1 gene were repeatedly detected in unrelated high-risk Czech breast and/or ovarian cancer families: p.Met18Lys (M18K); p.Cys39Arg (C39R); p.Cys61Gly (C61G). The RING finger motif of BRCA1 gene is involved in protein-protein interactions. The p.Cys61Gly is frequent mutation and was proved by many authors to segregate with the disease in several breast cancer families. However, p.Met18Lys detected in 3 Czech families is not recently present in BIC database and p.Cys39Agr detected in 3 Czech families has been submitted only twice to BIC database. None of these missense mutations was present

    Missense mutace v oblasti RING finger domény BRCA1 genu detekované u vysoce rizikových českých pacientek s hereditárním nádorem prsu a ovaria

  • Czech description

    Zárodečné mutace ve vysoce penetrantním genu BRCA1 způsobují predispozici k nádorům prsu a ovaria. Mutace, které způsobují stop kodon, jsou považovány za patogenní. Rozlišení patogenních missense mutací od polymorfismů je složité. Tři různé missense mutace lokalizované v konzervované oblasti C3HC4RING finger domény BRCA1 genu byly opakovaně nalezeny v českých rizikových rodinách s nádory prsu a/nebo ovaria: : p.Met18Lys (M18K); p.Cys39Arg (C39R); p.Cys61Gly (C61G). RING finger motiv genu BRCA1 je zapojen do protein-protein interakce. Mutace p.Cys61Gly je nacházena často a mnoha autory bylo potvrzeno, že segreguje s onemocněním v různých rodinách s nádory prsu. Mutace p.Met18Lys byla nalezena ve 3 českých rodinách a nebyla zatím publikována v BIC databázi. Mutace p.Cys39Arg byla nalezena také ve třech českých rodinách a v BIC databázi je zmíněna jen dvakrát. Žádná z těchto mutací nebyla nalezena v kontrolní populaci 50 zdravých postmenopausálních žen bez osobní a rodinné anamnézy nádoro
