Research on Rare Diseases in Germany - The cancer predisposition syndrome registry.

Background: Cancer predisposition syndromes (CPS) are rare diseases that are associated with an increased risk of cancer due to genetic alterations. At least 8 % of all cases of childhood cancer are attributable to CPS [1, 2]. The CPS registry was launched in 2017 to learn more about CPS and to improve the care to those afflicted by these diseases.

Health-related quality of life and fear of progression in individuals with Li-Fraumeni syndrome.

Li-Fraumeni syndrome (LFS) is a rare autosomal dominant cancer predisposition syndrome associated with a highly elevated lifetime cancer risk. This and the recommended intense surveillance program represent a large psychological burden on families. In order to develop targeted psychosocial interventions, we conducted a needs assessment.

Genotype-phenotype associations within the Li-Fraumeni spectrum: a report from the German Registry.

Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome caused by pathogenic TP53 variants. The condition represents one of the most relevant genetic causes of cancer in children and adults due to its frequency and high cancer risk. The term Li-Fraumeni spectrum reflects the evolving phenotypic variability of the condition.

Cancer in Children With Fanconi Anemia and Ataxia-Telangiectasia-A Nationwide Register-Based Cohort Study in Germany.

Purpose: Fanconi anemia (FA) and ataxia-telangiectasia (AT) are rare inherited syndromes characterized by abnormal DNA damage response and caused by pathogenic variants in key DNA repair proteins that are also relevant in the pathogenesis of breast cancer and other cancer types. The risk of cancer in children with these diseases is poorly understood and has never been assessed in a population-based cohort before.

Methods: We identified 421 patients with FA and 160 patients with AT diagnosed between 1973 and 2020 through German DNA repair disorder reference laboratories.
