Study Notes
Inborn Errors of Metabolism
- Inborn errors of metabolism usually stem from a deficiency of a specific enzyme, affecting biochemical pathways and leading to metabolic disorders.
Environmental Factors in Disease Expression
- Environmental factors significantly interact with genetics to influence disease severity, underscoring the complexity of disease predisposition and expression.
Evidence-Based Medicine (EBM)
- The first step in the UMMS EBM cycle is to "Ask," initiating the process of seeking evidence-based answers.
- Evidence-Based Medicine combines best research evidence with clinical expertise and patient values to optimize patient care.
Genetic Counseling
- Genetic counseling focuses on helping patients understand and adapt to the genetic contributions to their health and diseases.
- A common reason for referral to genetic counseling is multiple family members affected by the same or related disorders.
Gene-/Nucleic Acid-Based Therapies
- Gene addition therapy aims to increase the levels of proteins that are deficient or absent due to genetic conditions.
- Frameshift mutations alter the reading frame for protein synthesis, potentially leading to significant functional changes in proteins.
Pharmacogenetics and Precision Medicine
- Pharmacogenetics studies how genetic variations affect individual drug responses, aiming to tailor drug therapies to genetic profiles.
- Precision medicine personalizes treatment plans based on the unique genetic makeup of individuals, enhancing treatment effectiveness.
Genetic Analysis Techniques
- The term "heterozygous" refers to having two different alleles at a genetic locus, which can affect trait expression.
- A higher prevalence of a disease in genetically related individuals suggests a genetic basis for that disease.
Genetic Counseling & Medical Genetics
- Genetic counseling typically involves interpreting family and medical histories and discussing the implications of genetic testing but does not include surgical interventions.
- Common genetic conditions requiring counseling include inherited disorders like cystic fibrosis and Tay-Sachs disease.
Gene Editing & Cell Therapy
- CRISPR-Cas9 is a gene editing tool that utilizes guide RNA coupled with a Cas9 enzyme to precisely modify DNA.
- CAR-T cell therapy modifies T cells to specifically target and eliminate cancer cells, enhancing cancer treatment efficacy.
Advanced Genetic Techniques
- "In vivo" gene therapy refers to the direct delivery of therapeutic agents into the body, allowing for immediate treatment effects.
- "Ex vivo" gene therapy involves modifying cells outside the body and then reintroducing them, enabling targeted therapy for specific conditions.
