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.
