What is the proposed molecular mechanism by which MECP2 dysfunction causes the neurological features of Rett syndrome?
pubmed:17289941 makes a specific, notable claim that Rett syndrome neurons do NOT die ("this is not a neurodegenerative disorder") despite the severe phenotype — a nuance that distinguishes Rett's mechanism from most other tasks in this benchmark (e.g. D-002 Alexander disease, D-005 Huntington disease) which DO involve neurodegeneration/cell loss. A system that defaults to "neurodegeneration" without checking this specific corpus evidence would get this task's key distinguishing detail wrong.

MECP2 dysfunction leads to elevated DNA damage in neurons.
MECP2 interacts with members of the DNA repair machinery, including PARP1.
Restoration of PARP1 activity in MECP2-null neurons can reverse DNA damage, senescence, dendritic branching defects, and metabolic dysfunction.
