Study Notes
- Step 4 involves genotype statistics summary, filtering, population stratification, and association tests.
- SNP & Variation Suite (SVS) is a GUI-based software for genotype analysis.
- Filtering parameters include call rate, minor allele frequency, Hardy-Weinberg equilibrium, and number of alleles.
- Principal component analysis and Q-Q plot can be used for population stratification detection and adjustment.
- Step 5 involves variant annotation using public variant databases and tools such as PolyPhen and SIFT.
- ANNOVAR is a command-line tool for functional genetic variant annotation.
- Step 6 involves variant visualization using tools such as Integrative Genomics Viewer (IGV) and Circos.
- IGV can display BAM, VCF, SNP, LOH, and SEG formats and reveal variant relationships with annotations.
- Circos is a command-line tool for visualizing variant relationships between multiple genomes and displaying various types of variants and annotations in the same figure.
- Variant annotations and visualizations can aid in identifying potential causative variants for disease susceptibility, severity, outcome, and treatment response.
