F8A1, Official Symbol F8A1provided by HGNC Official Full Name coagulation factor VIII associated 1provided by HGNC Primary source HGNC:HGNC:3547 See related Ensembl:ENSG00000288722 MIM:305423; AllianceGenome:HGNC:3547 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as F8A; HAP40; DXS522E Summary This gene is contained entirely within intron 22 of the factor VIII gene; spans less than 2 kb, and is transcribed in the direction opposite of factor VIII. A portion of intron 22 (int22h), containing F8A, is repeated twice extragenically closer to the Xq telomere. 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
