Chromosome 6 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 6, one copy inherited from each parent, form one of the pairs. Chromosome 6 spans about 171 million base pairs (the building blocks of DNA) and represents between 5.5 percent and 6 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 6 likely contains between 1,100 and 1,600 genes.

Genes on chromosome 6 are among the estimated 20,000 to 25,000 total genes in the human genome.

Australian researchers identify thousands with curable high blood pressure

Team of researchers led by Professor Richard Gordon and Associate Professor Michael Stowasser has found primary aldosteronism (PAL) , a type of high blood pressure that can be cured by surgery , to be ten times more common than was previously suspected.

New automated test for gene mutations causing fragile X syndrome

A new automated test could enable population screening to identify carriers of the gene mutations causing fragile X syndrome (FXS), the most common inherited form of mental retardation, reports a study in the April issue of Genetics in Medicine, published by the American College of Medical Genetics and Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
