Subcellular Localization
Disease Associations Deafness, X-linked, 4 (DFNX4) [MIM:300066]: A non- syndromic form of sensorineural, progressive hearing loss with postlingual onset. In affected males, the auditory impairment affects initially high-frequency hearing. It later evolves to become severe to profound and affects all frequencies. Carrier females manifest moderate hearing impairment in the high frequencies. {ECO:0000269PubMed:21549336, ECO:0000269PubMed:21549342, ECO:0000269PubMed:22911656}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Preferentially and abundantly expressed in heart and skeletal muscle.
