Chromosome 7 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 7 spans about 159 millionbase pairs (the building material of DNA) and represents between 5 and 5.5 percent of the total DNA in cells.

The following are some of the gene count estimates of human chromosome 7. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction).

When simply saying "number of genes", in most cases, it refers only to "number of protein-coding genes".

Some of the genes found on human chromosome 7 are:

The following diseases are some of those related to genes on chromosome 7:

The following conditions are caused by changes in the structure or number of copies of chromosome 7:

While a few of the specific genes related to Williams syndrome have been identified, the relationship between most of the genes in the deleted region and the signs and symptoms of Williams syndrome is unknown.

In the novel Performance Anomalies, researchers at Stanford University identify mutations in the long (q) arm of chromosome 7 as underlying the accelerated nervous system of the spy protagonist Cono, who receives the moniker Cono 7Q
