GET3 and Parkinson disease: The International Parkinson's Disease Genomics Consortium (IPDGC) dataset shows 2 missense and 1 frameshift mutations in PTEN (all in PD cases, no rare variants were found in controls); 4 missense, 1 frameshift and 1 stop-gained mutations in ASNA1; and 5 missense and 1 deletion mutations in VAPB. With the exception of three common variants in VAPB, all others are exceedingly rare in the population (Table 4) and heterozygous in the IPDGC dataset.
