Multiple genes linked to familial primary brain calcification (PFBC) include SCL20A2, PDGFB, PDGFRB, and XPR1, all associated with Fahr's disease.
A systematic review analyzed 137 cases of PFBC and 20 cases of pseudohypoparathyroidism through recent literature, highlighting clinical and genetic correlations.
Findings revealed SLC20A2 as the most common gene involved, with notable clinical symptoms linked to specific genetic mutations, leading to a proposed diagnostic algorithm for affected patients.
