Single Nucleotide Polymorphisms (SNPs) are the most abundant and widely studied form of genetic variation in the human genome. They occur when a single nucleotide—A, T, C, or G—in the DNA sequence is altered. These subtle variations are found throughout the genome and are responsible for individual differences in traits, disease susceptibility, and responses to medications.
🔍 Why Are SNPs Important?
SNPs play a pivotal role in modern genomics. Their analysis enables:
- Pharmacogenomics: Tailoring drug treatments to genetic profiles.
- Disease Risk Prediction: Identifying individuals more prone to conditions like cancer, diabetes, and Alzheimer’s.
- Genetic Diagnosis: Detecting inherited disorders and carrier status.
- Agricultural Genomics: Improving crop yields and livestock traits through SNP marker-assisted selection.
🧪 How Are SNPs Detected?
Several molecular and computational techniques are available for SNP detection:
- PCR-based methods (e.g., ARMS-PCR, TaqMan Assays)
- Sanger and Next-Generation Sequencing (NGS)
- SNP microarrays and DNA chips
- Bioinformatics tools such as BLAST, UCSC Genome Browser, and Ensembl
The choice of technique depends on the study’s goals, budget, and required resolution.
🧬 Applications of SNP Analysis
SNPs are foundational in:
- Personalized medicine: Determining how an individual will respond to a drug.
- Cancer diagnostics: Detecting mutations in tumor suppressor genes.
- Forensics and ancestry tracing: Mapping genetic lineage and individual identity.
- Population genetics and evolution: Understanding human history and migration patterns.
