Homeobox protein Hox-A1 is a protein that in humans is encoded by the HOXA1 gene.[5][6][7]
Gene
Two
homeodomain region.[8]
Function
In vertebrates, the genes encoding the class of
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 cellular differentiation. The homeobox protein Hox-A1 may be involved in the placement of hindbrain segments in the proper location along the anterior-posterior axis during development.[8]
Clinical significance
A common polymorphism in the HOXA1 gene is associated with a susceptibility to
superior olivary nuclei), as well as induce several other physical changes such as in ear shape.[10]
Both of these sets of changes can also be seen in patients with autism.
Other HOXA1 mutations are associated with Bosley-Salih-Alorainy syndrome (BSAS) or the Athabaskan brainstem dysgenesis syndrome (ABDS).[11]
