At about 21.5 genes per megabase, chromosome 11 is one of the most gene-rich, and disease-rich, chromosomes in the human genome. More than 40% of the 856 olfactory receptor genes in the human genome are located in 28 single-gene and multi-gene clusters along the chromosome.
23 mar 2006 · Figure 1 shows an overview of the chromosome 11 landscape. HSA11 is very gene rich and there are many clustered gene families located on the chromosome.
For example, the hemoglobin beta gene (HBB) is found on chromosome 11p15.4. This means that the HBB gene lies on the short arm (p) of chromosome 11 and is found at the band labeled 15.4. With the advent of new techniques in DNA analysis, we are able to look at the chromosome in much greater detail.
3 wrz 2023 · Chromosome 11 is one of the 23 pairs of chromosomes that are present in humans. It is a critical chromosome that contains many important genes related to intellectual and developmental conditions. Several genetic rearrangements and deletions that affect chromosome 11 have been described, leading to various health conditions.
Researchers have identified genes on the short arm of chromosome 11 that are associated with particular features of WAGR syndrome. A loss of the PAX6 gene disrupts normal eye development, leading to aniridia and other eye problems, and may also affect the development of the brain.
Chromosome 11 is singular in that it carries hosts of genes involved in various illnesses. At least 180 genes involved in perceiving smells are found on the chromosome.
21 lip 2013 · This video produced by Cold Spring Harbor Laboratories takes us on a tour of about 650,000 nucleotides from the tip of the short arm of human chromosome 11. From a distance we can discern 28 genes, denoted by red and yellow blocks.
