Hereditary Tumor Syndromes and Phacomatoses
摘要
Approximately 5–10% of all cancers (CA) arise due to a hereditary cause. To date, over 110 cancer-predisposing genes have been identified, with approximately 60% of predispositions following an autosomal dominant (AD) and around 25% an autosomal recessive (AR) inheritance pattern. In about 15% of tumor predispositions, both an AD phenotype (adult-onset cancer) and an AR phenotype (childhood cancer) are abserved (e.g., mismatch repair (MMR) genes in Lynch syndrome).
