About ARX

Cytogenetic location: Xp21.3 Genomic coordinates (GRCh38): X:25,003,694-25,015,965 (from NCBI)

This gene has 5 transcripts (splice variants), 209 orthologues, 50 paralogues and is associated with 15 phenotypes. Biased expression in ovary (RPKM 16.9), brain (RPKM 2.3) and 2 other tissues.

Summary

This gene is a homeobox-containing gene expressed during development. The expressed protein contains two conserved domains, a C-peptide (or aristaless domain) and the prd-like class homeobox domain. It is a member of the group-II aristaless-related protein family whose members are expressed primarily in the central and/or peripheral nervous system. This gene is thought to be involved in CNS development. Expansion of a polyalanine tract and other mutations in this gene cause X-linked cognitive disability and epilepsy.
