Genes affected
ALX1 (HGNC:1494): (ALX homeobox 1) The specific function of this gene has yet to be determined in humans; however, in rodents, it is necessary for survival of the forebrain mesenchyme and may also be involved in development of the cervix. Mutations in the mouse gene lead to neural tube defects such as acrania and meroanencephaly. [provided by RefSeq, Jul 2008]
ALX1 Gene-Disease associations (from GenCC):
  • frontonasal dysplasia - severe microphthalmia - severe facial clefting syndrome
