    • Ancestry of the brazilian TP53 c.1010G>A (p. Arg337His, R337H) founder mutation : clues from haplotyping of short tandem repeats on chromosome 17p 

      Paskulin, Diego D'Ávila; Giacomazzi, Juliana; Achatz, Maria Isabel Alves de Souza Waddington; Costa, Sandra; Reis, Rui Manoel; Hainaut, Pierre; Santos, Sidney Emanuel Batista dos; Prolla, Patrícia Ashton (2015) [Journal article]
      Rare germline mutations in TP53 (17p13.1) cause a highly penetrant predisposition to a specific spectrum of early cancers, defining the Li-Fraumeni Syndrome (LFS). A germline mutation at codon 337 (p.Arg337His, c1010G>A) ...
    • Increased oxidative damage in carriers of the germline TP53 p.R337H mutation 

      Macedo, Gabriel de Souza; Motta, Leonardo Lisbôa da; Giacomazzi, Juliana; Netto, Cristina Brinckmann Oliveira; Manfredini, Vanusa; Vanzin, Camila Simioni; Vargas, Carmen Regla; Hainaut, Pierre; Klamt, Fabio; Prolla, Patrícia Ashton (2012) [Journal article]
      Germline mutations in TP53 are the underlying defect of Li-Fraumeni Syndrome (LFS) and Li-Fraumeni-like (LFL) Syndrome, autosomal dominant disorders characterized by predisposition to multiple early onset cancers. In Brazil, ...
    • Prevalence of the TP53 p.R337H mutation in breast cancer patients in Brazil 

      Giacomazzi, Juliana; Graudenz, Márcia Silveira; Osório, Cynthia Aparecida Bueno de Toledo; Santos, Patrícia Koehler dos; Palmero, Edenir Inêz; Oliveira, Marcelo Zagonel de; Michelli, Rodrigo Augusto Depieri; Scapulatempo Neto, Cristovam; Fernandes, Gabriela de Carvalho; Achatz, Maria Isabel Alves de Souza Waddington; Martel-Planche, Ghyslaine; Soares, Fernando A.; Caleffi, Maira; Goldim, José Roberto; Hainaut, Pierre; Camey, Suzi Alves; Prolla, Patrícia Ashton (2014) [Journal article]
      Germline TP53 mutations predispose individuals to multiple cancers and are associated with Li-Fraumeni/Li-Fraumeni-Like Syndromes (LFS/LFL). The founder mutation TP53 p.R337H is detected in 0.3% of the general population ...
    • Screening for germline BRCA1, BRCA2, TP53 and CHEK2 mutations in families at-risk for hereditary breast cancer identified in a population-based study from Southern Brazil 

      Palmero, Edenir Inêz; Temes, Bárbara Alemar Beserra; Faccini, Lavinia Schuler; Hainaut, Pierre; Moreira Filho, Carlos Alberto; Ewald, Ingrid Petroni; Santos, Patrícia Koehler dos; Ribeiro, Patrícia Lisbôa Izetti; Netto, Cristina Brinckmann Oliveira; Kelm, Florence Le Calvez; Tavtigian, Sean V.; Cossio, Silvia Liliana; Giugliani, Roberto; Caleffi, Maira; Prolla, Patrícia Ashton (2016) [Journal article]
      In Brazil, breast cancer is a public health care problem due to its high incidence and mortality rates. In this study, we investigated the prevalence of hereditary breast cancer syndromes (HBCS) in a population-based cohort ...
    • The TP53 fertility network 

      Paskulin, Diego D'Ávila; Paixão Côrtes, Vanessa Rodrigues; Hainaut, Pierre; Bortolini, Maria Cátira; Prolla, Patrícia Ashton (2012) [Journal article]
      The TP53 gene, first described in 1979, was identified as a tumor suppressor gene in 1989, when it became clear that its product, the p53 nuclear phosphoprotein, was frequently inactivated in many different forms of cancers. ...
    • TP53 mutation p.R337H in gastric cancer tissues of a 12-year-old male child - evidence for chimerism involving a common mutant founder haplotype : case report 

      Silva, Edaise M. da; Achatz, Maria Isabel Alves de Souza Waddington; Martel-Planche, Ghyslaine; Montagnini, André L.; Olivier, Magali; Prolla, Patrícia Ashton; Hainaut, Pierre; Soares, Fernando A. (2011) [Journal article]
      Background: Gastric adenocarcinoma is rare in children and adolescents, with about 17 cases under age 21 in the world’s literature. We report a case of invasive well-differentiated metastatic gastric cancer in a Brazilian ...
