Uncoupling of CSF biomarkers and clinical status in patients with a novel mutation of ATP13a2 Open
Summary Cerebrospinal fluid (CSF) biomarkers are generally assumed to reflect the severity and progression of neurodegenerative disease. We report three siblings carrying a novel heterozygous ATP13A2 variant (p.Pro629Ser) who challenge thi…

Is <i>CABP2</i> ‐Associated Hearing Loss (DFNB93) a Gene Therapy Target? Preclinical Progress and Patient Registry Open
CABP2 modulates presynaptic Ca V 1.3 Ca 2+ channel function in inner hair cells (IHCs) and is required for indefatigable synaptic sound encoding. Biallelic variants in CABP2 are associated with non‐syndromic hearing loss (DFNB93). Otoacous…
