Chromosome 19 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 19 spans more than 58.6 million base pairs, the building material of DNA. 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. Depending on the genome annotation used, chromosome 19 contains 2,188 or 2,670 genes, and chromosome 19 thereby has the highest gene density of all the 24 chromosomes. ==Genes== The following are some of the genes located on chromosome 19: * KLK3: The Prostate-specific antigen (PSA) * NWD1: NACHT and WD repeat domain containing 1. * PEX11G: peroxisomal biogenesis factor 11 gamma * PRX: Periaxin * SLC5A5: Solute carrier family 5 (sodium iodide symporter), member 5 * STK11: Serine/threonine kinase 11 (Peutz-Jeghers syndrome) * ZNF649: Transcriptional suppressor 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chromosome 19 (human)」の詳細全文を読む スポンサード リンク
