Human chromosome 9 is a submetacentric chromosome that accounts for 4% of the human genome. It contains an unusually extensive pericentromeric heterochromatic region and gene clusters encoding, among other proteins, the -interpherons and olfactory receptors.
Keywords: genetic map; physical map; HChr9; submetacentric; homology; genetic disease
