UCHL1 and tuberous sclerosis: UCH-L1 levels in CSF did not differ significantly between the TSC (median 325.7, range 106.3–1340 pg/mL), Ctrl-T (median 272.9, range 128.1–676.1 pg/mL), and Ctrl-R (median 133.6, range 37.9–280.1 pg/mL) groups, though there was a trend towards increased levels in TSC (Fig. 4b).
