Rare Variant Analysis of PTRHD1 in Parkinson's Disease in the Chinese Population

Homozygous missense variants in PTRHD1 have been identified to cause parkinsonism by segregation analysis in families. Further replication in the Parkinson's disease (PD) population might provide additional insight. Here, we analyzed the rare variants in a Chinese PD cohort (Ncase = 1367, Ncontrol = 3298) with whole exome sequencing. We did not identify the variants described in previous studies, and no patient carried other homozygous or compound heterozygous variants of PTRHD1. Three rare variants were identified, but rare variants of PTRHD1 were not enriched in PD. Genetic screening suggested rare variants of PTRHD1 as disease cause were rare in PD in East Asians.
