Study objectives

Recently, IMPDH2 has been linked to dystonia. However, no replication study from other cohorts has been conducted to confirm the association. We aimed to systematically evaluate the genetic associations of IMPDH2 with dystonia in a large dystonia cohort.

Methods

We analyzed rare variants (minor allele frequency < 0.01) of IMPDH2 in 688 Chinese dystonia patients with whole exome sequencing. The over-representation of rare variants in patients was examined with Fisher's exact test at allele and gene levels.

Results

Four rare variants were detected in IMPDH2 in four patients with dystonia in our cohort, including three missense variants (p.Ser508Leu, p.Ala396Thr, and p.Phe24Val) and one splice acceptor variant (c.1296-1G>T). Two of them (c.1296-1G>T and p.Ser508Leu) were co-segregated in the family co-segregation analysis and were classified as pathogenic and likely pathogenic variant according to the American College of Medical Genetics and Genomics (ACMG) guidelines, respectively. Gene burden analysis revealed enrichment of rare variants in IMPDH2 in dystonia.

Conclusions

Our work supplemented the evidence on the role of IMPDH2 in autosomal dominant dystonia in Chinese population, and expanded the genetic and phenotypic spectrum of IMPDH2, paving way for future studies."xsd:string
