Gene Gene information from NCBI Gene database.
Entrez ID 23676
Gene name Small muscle protein X-linked
Gene symbol SMPX
Synonyms (NCBI Gene)
ChiselCslDFN6DFNX4MPD7
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
