WebThese options only filter on the presence of the flag and not its value. These options can be used multiple times to specify multiple INFO flags. ALLELE FILTERING--maf --max-maf Include only sites with a Minor Allele Frequency greater than or equal to the "--maf" value and less than or equal to the "--max-maf" value. http://www.gnomad-sg.org/help/faf
WebJun 13, 2024 · We repeated the analysis for variants filtered according to various minor allele frequency and protein consequence thresholds that researchers may use when filtering variants. First, we filtered out common variants that met various minor allele frequency (MAF) thresholds used in the literature and others: 5, 1, 0.5, 0.1 and 0.05%. http://cardiodb.org/allelefrequencyapp/#:~:text=If%20the%20filter%20allele%20frequencyof%20a%20variant%20is,to%20the%20%E2%80%9Cfilter_AF%E2%80%9D%20annotation%20in%20the%20ExAC%20dataset.
WebWe propose that this behaviour is caused by the combination of a drop in the total size of the data matrix and by correlations between allele frequencies and mutational age. We recommend a set of best practices for applying MAF filters in studies seeking to describe population structure with genomic data. WebJun 5, 2024 · For allele frequency filtering, we left the uncertainty up to the user, inviting people to set conservative limits on what values they would believe for disease prevalence and proportion of cases attributable to a variant, and a minimum penetrance that they cared about, and then computing a loose upper bound on what allele frequency was ...
