WebThe prevalence of ATTRv in the world population was 57.4/100,000. Two variants (2 allele counts) and 15 variants (34 individuals) were defined as pathogenic variants in the ChinaMAP database and the Amcarelab exome database, respectively. Thus, the estimated prevalence interval of ATTRv in mainland China was 18.9/100,000-74,9/100,000. WebTo find the allele frequencies, we again look at each individual’s genotype, count the number of copies of each allele, and divide by the total number of gene copies. Now, we find the frequency of W has dropped to 8/18 = 0.44 8/18 = 0.44, or 44%, and the … WebAllele Frequency: The frequency of occurrence or proportions of different alleles of a particular gene in a given population is called allele frequency.
