Genes affected

HOXA1 (HGNC:5099): (homeobox A1) In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. The encoded protein may be involved in the placement of hindbrain segments in the proper location along the anterior-posterior axis during development. Two transcript variants encoding two different isoforms have been found for this gene, with only one of the isoforms containing the homeodomain region. [provided by RefSeq, Jul 2008]

HOXA1 links:

HOTAIRM1 (HGNC:37117): (HOXA transcript antisense RNA, myeloid-specific 1) This non-coding locus is located in the HOX gene cluster. Transcription of this locus is induced by retinoic acid, and transcripts likely function in regulation of myelopoiesis through transcriptional activation of several genes in the HOXA cluster, in addition to several beta-2 integrins.
