F8A3, Official Symbol F8A3provided by HGNC Official Full Name coagulation factor VIII associated 3provided by HGNC Primary source HGNC:HGNC:31850 See related Ensembl:ENSG00000277150 AllianceGenome:HGNC:31850 Gene type protein coding RefSeq status VALIDATED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as HAP40 Summary This gene is part of a region that is repeated three times on chromosome X, once in intron 22 of the F8 gene and twice closer to the Xq telomere. This record represents the most telomeric copy. Although its function is unknown, the observation that this gene is conserved in the mouse implies it has some function. Unlike factor VIII, this gene is transcribed abundantly in a wide variety of cell types. [provided by RefSeq, Jul 2008] Orthologs all
