Types of Cancer-Related Genetic Mutations:
Inherited Germline Mutations: • BRCA1 and BRCA2 mutations increasing breast and ovarian cancer risk • Lynch syndrome genes predisposing to colorectal and endometrial cancers • TP53 mutations associated with Li-Fraumeni syndrome and multiple cancer types • PTEN mutations linked to hereditary cancer syndromes • Hereditary mutations passed from parents to children affecting cancer susceptibility
Acquired Somatic Mutations: • Mutations occurring during a person’s lifetime due to environmental factors • Oncogene activation promoting uncontrolled cell growth and division • Tumor suppressor gene inactivation removing normal growth controls • DNA mismatch repair gene mutations leading to genomic instability • Chromosomal rearrangements creating fusion genes with oncogenic potential
Significance in Treatment Planning: • Different mutations respond to specific targeted therapies • Genetic profiles help predict treatment effectiveness and resistance patterns • Mutation analysis guides clinical trial eligibility and treatment selection • Monitoring mutation changes helps track disease progression and treatment response • Family testing may be recommended based on inherited mutation patterns
