Figure 1 Reduced pedigrees of the 11 PFBC families with MYORG mutations. Arrow = proband; asterisk = DNA available; square = male; circle = female; diamond = male(s) or female(s); strikethrough = deceased individual; filled symbols = PFBC-affected individual; open symbols = relative assumed to be healthy; double dagger = relative with non-extensive brain calcifications. 001 = ID number; values in parentheses = age at onset; WT = reference allele.

Figure 2 Distribution of MYORG mutations on the protein, modified from Yao et al. (2018). The MYORG protein contains a short cytoplasm domain, a transmembrane fragment (black) and a long C-terminal luminal fragment with a glycosidase domain (striped area). Mutations reported in Yao et al. are represented at the top in grey, whereas mutations reported here are represented at the bottom, in black.

Figure 3 Calcifications scores of the MYORG patients compared to the AD-PFBC groups. (A) Heat map of the ascending hierarchical clustering of the calcification scores. All scores of right and left structures were summed (e.g. left lenticular nucleus plus right lenticular nucleus). Scores of the unique regions were doubled (vermis, pons, medulla) as well as the score of the cortex. In the upper part of the figure, the age of the patients when the CT scan was performed appear with colours corresponding to the genes: blue (PDGFRB), green (PDGFB), red (SLC20A2), black (XPR1) and purple (MYORG). SCWM = subcortical white matter. (B) Total calcification score (TCS) of all patients with available CT scan, according to the age at CT scan. The TCSs of MYORG patients were higher than those of SLC20A2 patients (P = 4.1 × 10⁻³), of PDGFB patients (P = 3.2 × 10⁻⁶), PDGFRB patients (P = 8.3 × 10⁻¹³) and XPR1 patients (but not statistically significant, P = 0.089).

Figure 5 VBM analysis showing SPMs of structural differences in grey matter between MYORG and AD-PFBC gene mutation carriers. Analysis was performed using normalized T₁-weighted MRI scans in MNI space, taking total intracranial volume, age and sex as covariates. SPMs were superimposed on a normalized T₁-weighted mean image of all patients and thresholded at P < uncorrected. Grey matter differences are colour coded (red-yellow) in terms of t-score as indicated on the colour bar (right).
