Despite the many advances in our understanding of the genetic basis of Mendelian
forms of Parkinson's disease (PD), a large number of early-onset cases still
remain to be explained. Many of these cases, present with a form of disease that
is identical to that underlined by genetic causes, but do not have mutations in
any of the currently known disease-causing genes. Here, we hypothesized that de
novo mutations may account for a proportion of these early-onset, sporadic cases.
We performed exome sequencing in full parent-child trios where the proband
presents with typical PD to unequivocally identify de novo mutations. This
approach allows us to test all genes in the genome in an unbiased manner. We have
identified and confirmed 20 coding de novo mutations in 21 trios. We have used
publicly available population genetic data to compare variant frequencies and our
independent in-house dataset of exome sequencing in PD (with over 1200 cases) to
identify additional variants in the same genes. Of the genes identified to carry
de novo mutations, PTEN, VAPB and ASNA1 are supported by various sources of data
to be involved in PD. We show that these genes are reported to be within a
protein-protein interaction network with PD genes and that they contain
additional rare, case-specific, mutations in our independent cohort of PD cases.
Our results support the involvement of these three genes in PD and suggest that
testing for de novo mutations in sporadic disease may aid in the identification
of novel disease-causing genes.
