About PHOX2A

Cytogenetic location: 11q13.4 Genomic coordinates (GRCh38): 11:72,239,077-72,244,176 (from NCBI)

This gene has 3 transcripts (splice variants), 190 orthologues, 50 paralogues and is associated with 3 phenotypes. Biased expression in adrenal (RPKM 6.0) and appendix (RPKM 0.4).

Summary

The protein encoded by this gene contains a paired-like homeodomain most similar to that of the Drosophila aristaless gene product. The encoded protein plays a central role in development of the autonomic nervous system. It regulates the expression of tyrosine hydroxylase and dopamine beta-hydroxylase, two catecholaminergic biosynthetic Enzymes essential for the differentiation and maintenance of the noradrenergic neurotransmitter phenotype. The encoded protein has also been shown to regulate transcription of the alpha3 nicotinic acetylcholine receptor gene. Mutations in this gene have been associated with autosomal recessive congenital fibrosis of the extraocular muscles. [provided by RefSeq, Jul 2008]
