    Mutations in BRCA1 result in predisposal to breast and ovarian cancers, but many variants exist with unknown clinical significance (VUS). One is BRCA1 c.4096+3A>G, which affects production of the full-length BRCA1 transcript, while augmenting transcripts ...

    Germline mutations in BRCA2 increase the risk of breast and ovarian cancer. The BRCA2 protein is involved in maintaining genomic stability through its roles in DNA double strand break repair and protection of stalled replication forks. The BRCA2 gene ...

    Recent studies indicate that lifestyle factors in early life affect breast cancer risk. We therefore explored the association of high consumption of meat, milk, and whole grain products in adolescence and midlife, on breast cancer risk. We used data ...
  • Stefánsdóttir, Vigdís (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-09)
    The overall aim of this PhD thesis was to cohesively assess the availability and use of electronic genealogy databases and information from cancer registries to construct electronically generated pedigrees for risk assessment in genetic counselling. ...

    The DNA damage response is crucial to maintaining the integrity of DNA and the health of a cell. Unrepaired lesions within the DNA can lead to genomic instability and potentially aid in the formation of diseases such as cancer. Some cancers possess ...
  • Figlioli, Gisella; Agnarsson, Bjarni A.; Barkardottir, Rosa Bjork (Springer Science and Business Media LLC, 2019-11-01)
    Breast cancer is a common disease partially caused by genetic risk factors. Germline pathogenic variants in DNA repair genes BRCA1, BRCA2, PALB2, ATM, and CHEK2 are associated with breast cancer risk. FANCM, which encodes for a DNA translocase, has ...
