We ask our users to note that this dataset does not represent mutation rates in absolute terms. All base substitutions recorded in HGMD are from mutations brought to clinical attention because they are disease causing. A method of compensating for this bias has been devised, and details can be found in Krawczak et al Am J Hum Genet 63:474-488, 1998. The results of the meta-analysis of single base-pair substitutions described in this paper are also available
