WebThe Fold change indicates whether a gene is up-regulated or down-regulated . For example, if we compare 2 experimental groups Wild Type versus Knock Out: Fold Change > 0 for gene A means that gene A is more expressed (= up-regulated) in Wild Type compared to Knock Out. Fold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A. In other words, a change from 30 to 60 is defined as a fold-change … See more There is an alternative definition of fold change, although this has generally fallen out of use. Here, fold change is defined as the ratio of the difference between final value and the initial value divided by the initial value. For … See more • A comparison of fold-change and the t-statistic for microarray data analysis See more In the field of genomics (and more generally in bioinformatics), the modern usage is to define fold change in terms of ratios, and not by the alternative definition.
