Several SLC20A2 mutations have been implicated as potential causes of Fahr's disease, a subtype of primary familial brain calcification (PFBC), but very few patient-derived induced pluripotent stem cell (iPSC) models have been established.

In conclusion, our study further confirms that mutations in SLC20A2 are the major cause of PFBC and provides additional evidence for the crucial roles of phosphate transport impairment in the pathogenies of PFBC.

This is the first study reporting sub-cellular expression analysis of mutant PiT-2 in primary cultured fibroblasts from a PFBC patient, showing that p.Trp626_Thr629dup in SLC20A2 alters PiT-2 sub-cellular localization and reduces Pi-uptake, leading to onset of PFBC in our patient.
