- Myoclonus
Some causes of objective tinnitus are head and neck vascular malformations, or muscular myoclonus of the tensor tympani, stapedial, or palatal muscles. [kz.tantalize.us]
Workup
For example if a KNCQ1 mutation is found, additional cardiac workup may be warranted since mutations in this gene are also associated with cardiac rhythm abnormalities. [bcidaho.com]

These factors lend credence to the theory that patients with GJB2 and GJB6 mutations may have a favorable prognosis following cochlear implantation, and that patients with other mutations or without a documented mutation may have a less favorable prognosis [bcidaho.com]
PTPRO can be reliably detected in peripheral blood samples, and is a potential biomarker in cancer diagnosis and prognosis. PTPRO has multiple isoforms. [phosphatome.net]
Acquired causes should be differentiated from genetic causes to inform the evaluation and required ancillary testing (i.e., CT, MRI, and consultation with specialists) and to inform prognosis and treatment recommendations. Figure 2. [ncbi.nlm.nih.gov]
