Mechanistic description
DPP6-linked neuronal regulatory networks controlling synaptic excitability and cognitive resilience in PD should produce a measurable proximal phenotype before late disease pathology. The decisive test is cell-type eQTL colocalization, enhancer perturbation, and prodromal PD single-nucleus validation in hippocampal and prefrontal neurons.
Mechanism / pathway
- DPP6
- neurodegeneration
Evidence for (1)
DPP6 was identified as a novel PD cognitive-decline risk gene; the paper noted that functional validation and cell-type-specific mechanisms remain uncharacterised.
Evidence against (1)
the GWAS signal may tag a nearby regulatory locus rather than DPP6 itself
Evidence matrix
Supporting
- DPP6 was identified as a novel PD cognitive-decline risk gene; the paper noted that functional validation and cell-type-specific mechanisms remain uncharacterised. GWAS Identifies DPP6 as Risk Gene of Cognitive Decline in Parkinson's Disease
Contradicting
- the GWAS signal may tag a nearby regulatory locus rather than DPP6 itself GWAS Identifies DPP6 as Risk Gene of Cognitive Decline in Parkinson's Disease
