PTPRD

PTPRD (protein tyrosine phosphatase receptor type D) encodes a neuronal cell-surface adhesion molecule that organizes synapse formation and has been linked to dopaminergic signaling pathways in the brain. PTPRD is one of the earliest and most consistently replicated GWAS loci for restless legs syndrome, a condition also tied to disrupted brain iron handling, which is why clinicians evaluate iron status alongside this genetic risk.
