The median disease duration from onset until death was 7.5 (range, 3.6–12) years in FGF14 GAA≥300 cases, 8.3 (range, 4–11) years in FGF14 GAA250–299 cases and 7.1 (range 3–12) years in FGF14 GAA-negative MSA cases, with no statistically difference between the groups. This evidence concerns the gene FGF14 and multiple system atrophy.
