Abstract
BACKGROUND Variants of the NUS1 gene have been associated with an extensive spectrum of phenotypes, including epilepsy, intellectual disability, cerebellar ataxia, Parkinson's disease, dystonia, and congenital disorder of glycosylation. It is rarely reported in progressive myoclonus epilepsy (PME). METHODS AND RESULTS Herein, we report the case of PME caused by a novel de novo NUS1 missense variant (c.302T>A, p.Met101Lys). In addition, we reviewed the current literature of NUS1-associated PME. At present, five patients with NUS1 variants and PME have been reported in the literature. Due to limited cases reported, the relationship between NUS1 variants and PME is not well-established. CONCLUSIONS Our case provides further evidence of the role of NUS1 variants in PME. These findings expand the clinical phenotypes of NUS1 variants, which should be included in the PME genetic screening panel.

Huang X, Zhao Y, Pan H, Wang Y, Liu Z, Xu Q, Sun Q, Tan J, Yan X, Li J, Tang B, Guo J. The association between LIN28A gene rare variants and Parkinson's disease in Chinese population. Gene 2022; 829:146515. [PMID: 35447238 DOI: 10.1016/j.gene.2022.146515] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 04/02/2022] [Accepted: 04/14/2022] [Indexed: 12/12/2022]
Abstract
Parkinson's disease (PD) is a neurodegenerative disease caused by aging, environmental and genetic factors, and many susceptibility genes have been found to increase the risk for PD. Lin28a, an RNA binding protein, is expressed prominently in neural progenitor cells. The expression of Lin28a is decreased gradually with neural differentiation and is implicated in oncogenesis, glucose metabolism, neurogenesis, and neurogliogenesis. However, few genetic studies have explored the association between rare variants of the LIN28A gene and PD yet. Our study recruited 3,879 PD patients and 2,931 controls, and they were divided into two cohorts, including the EOPD & FPD cohort and the LOPD cohort, separately sequenced by whole-exome sequencing and whole-genome sequencing. We found nine rare nonsynonymous variants in the coding region of the LIN28A gene, but the rare variants of this gene were not enriched in PD patients in both cohorts. Thence, our study did not support the association between the LIN28A gene and the PD risk in the Chinese mainland population.
