    Researchers have found surprising variation in the number of genes on human chromosomes 13 and 19, in addition to gene sequences associated with a range of diseases, in the full sequencing of the genes published for the first time last week.

    The first full sequences of the two human chromosomes showed a large difference in the numbers of genes coded for by the two chromosomes. Sequencing showed that human chromosome 13 contained more than 95.5 megabases (one megabase is a million base pairs), within which there were 633 genes (Nature 2004;428: 522-8).In contrast, chromosome 19 was smaller, at …
