Analysis of 2 Human Chromosomes Finished
From Times Staff and Wire Reports
Scientists have completed the final analysis of two more human chromosomes.
Chromosome 19 with nearly 1,500 genes, including some linked to high cholesterol and insulin-resistant diabetes, is the most gene-dense of those sequenced. By contrast, chromosome 13 has one of the lowest concentrations of genes with only 633. But they include the BRCA2 gene linked to breast cancer and others linked to bipolar disorder and schizophrenia. The sequences of chromosomes 19 and 13 were published in the current issue of the journal Nature.
