lecture 4/5
what is the goal of 1000 genomes project (1KGP)?
to create a detailed catalogue of human genetic variation by sequencing the genomes of at least 1000 individuals from various ethnic groups
who participated in the 1KGP?
2504 healthy individuals from 26 human populations
what was read in the 1KGP?
short-read DNA sequencing
what was the major finding regarding profiles from the 1KGP?
individuals from different populations carry different profiles of rare and common variants
what were the other major findings of the 1KGP?
low frequency variants show substantial geographic differentiation
on average, each person carries around 250-300 loss of function variants in annotated genes and 50-100 variants previously implicated in inherited disorders
how many loss of function variants are in annotated genes on average?
250 to 300
what is the Ensembl variation database?
stores areas of the genome that differ between individual genomes (variants) and where available, associated disease, and phenotype information
what are the different types of variants in the 1KGP?
single nucleotide polymorphism (SNPs)
short nucleotide insertions and/or deletions
longer variants classified as structural variants (including CNVs)
what is the first place you should check for pharmacogenomics information?
PHARMGKB
what does prescribing info say in PHARMGKB?
explains how to adjust treatment of certain medication based on a person’s genetic information
includes information from clinicial guideline annotations, drug label annotations, and RX study annotations
what are PharmGKB annotations present?
a brief summary of the genotype-based dosing recommendations and links to the source publication/documents
