Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 15, one copy inherited from each parent, form one of the pairs. Chromosome 15 spans about 100 million base pairs (the building blocks of DNA) and represents more than 3 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 15 likely contains between 650 and 1,000 genes.
Genes on chromosome 15 are among the estimated 20,000 to 25,000 total genes in the human genome.
A team of researchers from the University of Chicago, in collaboration with the Free University of Brussels and the University of Washington, have uncovered a genetic mutation in a non-coding region of DNA that alters the regulation of the thyroid, leading to a rare form of congenital thyroid abnormality.
In 2019, the WHO positioned chronic obstructive pulmonary disease (COPD) third in the global ranking of causes of death.
A study performed on canines at the University of Helsinki characterizes a gene variant in the regulatory region of the retina that causes abnormal functioning of retinal genes and, ultimately, leads to loss of vision in dogs.
