SLC26A5 and Parkinson disease: Introducing mutations N7T and N308S into Prestin and transfecting it into human HEK293T cells, they found that the mPrestin(N7T, N308S) group had a higher percentage of cells responsive to 0.5 MHz focused ultrasound compared to the wild‐type group.[103] In 2020, Yeh et al used a non‐invasive gene delivery method for Prestin and observed increased c‐Fos staining in cells expressing Prestin.[104] Next year, mPrestin(N7T, N308S) was expressed in the dopaminergic neurons of Parkinson's disease mice in the substantia nigra.
