Chromosome 3 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 3, one copy inherited from each parent, form one of the pairs. Chromosome 3 spans almost 200 million base pairs (the building blocks of DNA) and represents approximately 6.5 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 3 likely contains between 1,100 and 1,500 genes.

Genes on chromosome 3 are among the estimated 20,000 to 25,000 total genes in the human genome.

Surprising discovery in people of Polynesian ancestry offers clues to genetic underpinnings of high cholesterol

The discovery of a genetic variant that is relatively common among people of Polynesian ancestry, but incredibly rare in most other populations, is giving clues to the genetic underpinnings of high cholesterol in all people, according to new research led by University of Pittsburgh School of Public Health geneticists in partnership with several other groups, including the University of Otago and the Samoan health research community.

New discovery changes the understanding of Duchenne muscular dystrophy

Duchenne muscular dystrophy (DMD) is caused by a genetic mutation and affects one in every 5,000 boys born. Because the affected gene is on the X chromosome, girls are carriers of the mutant gene but develop the disease only very rarely (one in about 50 million).

Study identifies genetic variation linked with posterior urethral valves in males

Genetic variation affecting developmental genes not previously linked to urethral development may contribute to a congenital condition that is the most common cause of kidney failure in young males, a study published today in eLife suggests.

Cell's anti-aging structures can set the damage threshold a cancer cell can sustain, study shows

A new study led by Claus M. Azzalin, group leader at Instituto de Medicina Molecular João Lobo Antunes- iMM and published today in the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS) shows, for the first time, that the cell's anti-aging structures – the telomeres – can set the damage threshold a cancer cell can sustain and above which cells cannot continue to divide and die.
