WDPCP and Tinnitus: As for the case of tinnitus, our particular WDPCP SNP is an asparagine to serine missense mutation, which may impede or alter the known functions of WDPCP. Because our final population lived to an elderly age and had no reports of major CNS conditions, we hypothesize that our WDPCP mutation may first cause malfunctions during embryonic development that are not severe enough to fully disrupt maintenance of cytoskeletal structure in neurons after this period.
