Chromosome 20

Number of genes The following are some of the gene count estimates of human chromosome 20. 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). Among various projects, the collaborative consensus coding sequence project (CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes. Gene list The following is a partial list of genes on human chromosome 20. For complete list, see the link in the infobox on the right. ==Diseases and disorders==

The following diseases are some of those related to genes on chromosome 20: • Albright's hereditary osteodystrophy • Arterial tortuosity syndrome • Adenosine deaminase deficiency • Alagille syndrome • Galactosialidosis - CTSA • Maturity onset diabetes of the young type 1 • Neuronal ceroid lipofuscinosis • Pantothenate kinase-associated neurodegeneration • Waardenburg syndrome type 4B • CARASAL ==Cytogenetic band==
