Sanger sequencing of the three prioritized variants in four additional affected (Fig. 1A, III:3, IV:4, IV:7 and IV:9) and eleven unaffected biological relatives excluded ZNF292 and C6orf163 variants and identified the stop-gain variant c.C811T; p.R271X in the PABPC4L gene as the possible cause of parkinsonian disorder in the family (Supplementary Table). Here, ZNF292 is linked to parkinsonian disorder.
