Study Notes
Gene Therapy
- The main goal of gene therapy is to treat or prevent diseases by introducing, removing, or altering genetic material within a patient's cells.
- Introducing exogenous (normal) genes into target cells aims to replace misfunctioning genes, restore normal function, and potentially cure genetic disorders.
Single Nucleotide Polymorphisms (SNPs)
- SNPs are variations in a single nucleotide that can influence individual susceptibility to diseases, including common migraine.
- They provide insights into genetic predispositions and mechanisms underlying diseases, aiding in personalized medicine approaches.
Cancer and Genetic Diseases Treatment
- Gene editing techniques show potential in treating various conditions, including cancer, thalassemia, and hemophilia, with methods like CRISPR-Cas9 being pioneering in this area.
Structural Variations in Diseases
- Structural variations are significant in understanding diseases like Alzheimer’s and other neurodegenerative diseases, impacting gene function and protein expression, which can lead to disease progression.
Bi-allelic Assays
- A method for bi-allelic assays that can detect DNA polymorphisms is the analysis of different alleles using techniques such as PCR and sequencing.
Fluorescence Ratio in DNA Tests
- The ratio of different fluorescence reporters in DNA polymorphism tests indicates the presence of specific alleles in a sample, assisting in genotype determination.
RFLP and Disease Detection
- RFLP (Restriction Fragment Length Polymorphism) can be utilized to detect diseases like cystic fibrosis and sickle cell anemia, revealing genetic mutations.
VNTR in DNA Polymorphism
- VNTR stands for Variable Number Tandem Repeats, a type of repetitive DNA sequence useful in DNA polymorphism detection.
- An article discussing the emerging role of VNTR in health and disease indicates its importance in genetic studies and disease understanding.
SNP Detection Techniques
- Techniques such as DNA sequencing and microarray analysis are typically used for detecting SNPs. Non-traditional methods include certain mass spectrometry techniques and high-resolution melting analysis.
Posttransplantation Chimerism Analysis
- Fluorescent multiplex PCR in posttransplantation chimerism analysis serves to quantify the proportions of donor and recipient cells, assessing the success of the transplantation.
Focus of Genomic Variant Studies
- The study of DNA polymorphisms, primarily SNPs, is crucial in understanding how genomic variants influence health and disease, providing a roadmap for targeted therapies.
Single Nucleotide Mismatch Detection
- Mismatch detection in traditional DNA polymorphism analysis is typically performed using techniques like melting temperature analysis, agarose gel electrophoresis, and ligation.
Informative Alleles Function
- In posttransplantation chimerism analysis using STR markers, informative alleles help distinguish between donor and recipient DNA, confirming the degree of chimerism.
Sex Identification Marker
- The SRY (Sex-determining Region Y) gene is a key genetic marker used to identify male individuals in chimerism analysis.
Mismatch Detection Effects
- Mismatch detection in DNA polymorphism analysis can destabilize DNA duplexes, leading to higher susceptibility to mutations and potentially influencing genetic disorder development.
