AI Article Synopsis

  • Recent studies identified mutations in the PTRHD1 gene linked to juvenile parkinsonism and intellectual disability in Iranian and African families, but their role in young-onset Parkinson's disease (PD) is still uncertain.
  • The researchers conducted a study with 464 participants, focusing on young-onset PD and familial cases, to investigate the presence of PTRHD1 mutations.
  • Their analysis revealed no pathogenic coding variants or previously identified mutations in the PTRHD1 gene among the Taiwanese cohort, indicating that these mutations are likely rare in this population for young-onset and familial PD.

Article Abstract

Mutations in the peptidyl-tRNA hydrolase domain containing 1 (PTRHD1) gene have been recently identified in consanguineous Iranian and African families with juvenile parkinsonism and intellectual disability. However, the pathogenicity of PTRHD1 mutations in the disease and their role in young-onset Parkinson's disease (PD) remains unclear. We aimed to investigate PTRHD1 mutations in a Taiwanese cohort with young-onset and familial PD. We enrolled 464 participants, including 178 probands from PD pedigrees without known PD-causative gene mutations and 286 patients with young-onset PD (age of onset <50 years). All exons and exon-intron boundary junctions of PTRHD1 were analyzed by Sanger sequencing. We did not find any pathogenic coding variants or previously reported mutations, suggesting that PTRHD1 mutations are rare in young-onset and familial PD in our population.

Nasopharyngeal cancer (NPC), although rare in young individuals worldwide, is significantly influenced by the Epstein-Barr virus (EBV). Considering EBV's widespread prevalence, understanding its role in NPC's future occurrence, disease progression, clinical symptoms, metastatic tendencies, and prognosis is crucial. In this study, we extensively analyzed two young patients with NPC, who displayed distinct clinical features.

Background: Data‐driven disease progression models of Alzheimer’s disease (AD) have identified subtypes in regional patterns of Aβ deposition using amyloid PET. In addition to Aβ accumulation, early frame measures of tracer delivery from amyloid PET are strongly correlated with blood flow. This work explores whether combining tracer delivery with amyloid binding measures can improve the subtype and stage characterisation over amyloid binding alone.

Background: Limbic‐predominant age‐related TDP‐43 encephalopathy (LATE) is often described as occurring in older individuals, either with or without co‐occurring neurodegenerative disease. Because the presence of LATE can only be determined post mortem, little is known about the clinical and neuroimaging features of LATE. The current study aims to assess the correlation between LATE and MRI‐measured amygdala and hippocampal volume in Alzheimer’s disease (AD) and Lewy Body Diseases (LBD), including Parkinson’s disease (PD), PD dementia, and dementia with Lewy Bodies

Methods: Post‐mortem in‐situ 3DT1 3T‐MRI data were collected for 51 cases (27 AD and 24 LBD) of which 17 had post‐mortem confirmed LATE neuropathological change (9 AD and 8 LBD), as well as 34 non‐LATE (18 AD and 16 PD) donors (matched on age, sex, and Braak stage).

Background: In clinical settings, the prognosis of patients with subtle cognitive complaints and no imaging evidence of neurodegeneration is often challenging, especially in conditions unrelated to Alzheimer’s Disease (AD). We aimed to identify which baseline indicators can help in the clinical decision‐making process of patients with Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) without AD pathology, by identifying those with faster brain atrophy for their age.

Method: Young‐onset SCD and MCI patients (symptoms ≤65yo) were recruited.

Background: Atypical presentations of Alzheimer’s disease (AD), which demonstrate more cortical involvement relative to medial temporal lobe (MTL), are generally associated with younger age of onset. Age, defined chronologically, is a primary driver of AD pathology and neurodegeneration. However, some young onset cases are typical, amnestic presentations and some older onset cases present more cortical atrophy.
