This is a real emerging area of research, I did some searching this morning and there are a few things around. There is research into auditory hallucination in schizophrenia that may or may not be relevant (beyond my level of understanding to know if it is
)
There is a fairly long read here although it's from 2012 -
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3491818/ - The conclusion section says:
miRNA involvement in the development and maturation of the inner ear and the auditory mechanism has been demonstrated numerous times. The most relevant to inner ear disease is the mutations in the seed region of miR-96, causing deafness in both humans and mice. This remarkable finding initiated a new paradigm in the deafness gene hunt. This was the first time that a single mutation in a miRNA was found to lead to deafness.
The implication that a single mutation in a miRNA can lead to deafness is not trivial, since it is not a direct result of the mutation, but rather, a result of many small cumulative events, caused by both the loss of inhibition on the miR-96 targets, and gain of function of the targets now recognized by the new mutated seed region. This complex disease-causing mechanism had led us to believe that there is much more to miRNA involvement in disease than previously known.
As new deep sequencing technologies are becoming more readily available, the miRNA field will rapidly grow and expand, identifying new miRNAs regulating important inner ear functions. Many diseases may be demonstrated to be affected by miRNA mutations, opening a vast potential for a future role for miRNAs as therapeutic agents.
