However, with the advent of genomic medicine, Sarah undergoes whole-genome sequencing to uncover the genetic basis of her disorder.
Bioinformatics Application
1. Data Processing Sarah's genomic data, consisting of billions of DNA base pairs, is processed using bioinformatics algorithms to filter out noise and identify relevant genetic variants. 2. Variant Analysis Bioinformatics tools compare Sarah's genetic sequence to reference genomes and databases to pinpoint variations associated with her condition. This analysis may reveal mutations in specific genes responsible for her metabolic disorder. 3. Functional Annotation Bioinformatics software annotates the identified genetic variants to assess their potential impact on protein function or gene regulation. This helps prioritize variants that are most likely to be causative. 4. Clinical Interpretation Bioinformaticians, in collaboration with medical geneticists, interpret the genomic findings in the context of Sarah's clinical presentation and family history. They determine the clinical significance of identified variants and their implications for diagnosis, prognosis, and treatment decisions. 5. Therapeutic Insights Insights from bioinformatics analysis may guide personalized treatment strategies for Sarah.
