SMPX (small muscle protein X-linked)

Gene

• Entrez ID: 23676
• Gene name: Small muscle protein X-linked
• Gene symbol: SMPX
• Synonyms: Chisel, Csl, DFN6, DFNX4, MPD7
• Chromosome: X
• Chromosome location: Xp22.12
• Summary: This gene encodes a small protein that has no known functional domains. Mutations in this gene are a cause of X-linked deafness-4, and the encoded protein may play a role in the maintenance of inner ear cells subjected to mechanical stress. Alternatively
