TMEM119 and Alzheimer disease: As CSF levels of TMEM119 were elevated in the AD cohort, we analyzed the association between CSF TMEM119 and the ATN biomarkers CSF t‐tau, p‐tau181, and Aβ1–42.43 CSF levels of TMEM119 were found to be weakly associated with CSF levels of t‐tau and p‐tau181 but not Aβ1–42 in the overall cohort.
