In order to evaluate the prevalence of RTT related to MECP2 mutations, we have carried out a systematic analysis of the MECP2 gene in 46 typical RTT patients and screened by DGGE (n = 38) and by direct sequencing (n = 8) the whole coding sequence of this gene. Upon analysis by DGGE of exon 1 to exon ...

Mutagen



In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
