Summaries for HOXA2 Gene

Entrez Gene Summary for HOXA2 Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for HOXA2 Gene

  • Microtia, hearing impairment, and cleft palate (MHICP) [MIM:612290]: A disease characterized by microtia, mixed symmetric severe to profound hearing impairment, and partial cleft palate. Microtia is a congenital deformity of the outer ear that is small and abnormally shaped. In classic microtia, the pinna is essentially absent, except for a vertical sausage-shaped skin remnant. The superior aspect of this sausage-shaped skin remnant consists of underlying unorganized cartilage, and the inferior aspect of this remnant consists of a relatively well-formed lobule. Syndromic forms of microtia occur in conjunction with other abnormalities including cleft palate, a congenital fissure of the soft and/or hard palate due to faulty fusion. {ECO:0000269 PubMed:18394579}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Microtia with or without hearing impairment (MCRT) [MIM:612290]: Microtia is a congenital deformity of the outer ear that is small and abnormally shaped.

The superior aspect of this sausage-shaped skin remnant consists of underlying unorganized cartilage, and the inferior aspect of this remnant consists of a relatively well-formed lobule. {ECO:0000269 PubMed:23775976}.
