abstract = {LIS1-lissencephaly is a neurodevelopmental disorder marked
by reduced cortical folding and severe neurological
impairment. Although all cases result from heterozygous
mutations in the LIS1 gene, patients present a broad
spectrum of severity. Here, we use patient-derived forebrain
organoids representing mild, moderate, and severe
LIS1-lissencephaly to uncover mechanisms underlying this
variability. We show that LIS1 protein levels vary across
patient lines and partly correlate with clinical severity,
indicating mutation-specific effects on protein function.
Integrated morphological, transcriptomic, and proteomic
analyses reveal progressive changes in neural progenitor
homeostasis and neurogenesis that scale with severity.
Mechanistically, microtubule destabilization disrupts
cell-cell junctions and impairs WNT signaling, and defects
in protein homeostasis, causing stress from misfolded
proteins, emerge as key severity-linked pathways.
Pharmacological inhibition of mTORC1 partially rescues these
defects. Our findings demonstrate that patient-derived
organoids can model disease severity, enabling mechanistic
dissection and guiding targeted strategies in
neurodevelopmental disorders.},
