Story summary

A study published in npj Parkinson’s Disease examines ITSN1's role in familial Parkinson's disease.
Researchers analyzed three novel families with ITSN1-linked Parkinson's symptoms to indicate ITSN1 may act as a Mendelian gene for Parkinson's.
The study highlights ITSN1's involvement in synaptic function and its potential as a precision medicine target.
Findings are promising but require confirmation in larger populations and further exploration of ITSN1 mutations' implications for counseling and treatment.
