Aims: Atrioventricular block (AVB) is a prevalent bradyarrhythmia. This study aims to investigate the causal effects of epigenetic aging, as inferred from DNA methylation profiles on the prevalence of AVB by Mendelian randomization (MR) analysis.
Methods: Genetic instruments for epigenetic aging and AVB were obtained from genome-wide association study data in the Edinburgh DataShare and FinnGen biobanks.

An African American man in his early 40s with progressive gait impairment and chronic cognitive impairment initially presented to the emergency department after statements of self-harm and was hospitalised. Examination revealed notable neurological abnormalities including impaired memory recall, oral dyskinesia/choreiform movements, dystonia of the right upper extremity with drift, hyper-reflexia and spastic gait. On further evaluation, including neurology and genetics consultation and workup, a clinical diagnosis of the neurodegenerative disorder Huntington's disease (HD) was made.

The APOE4 allele is the strongest genetic risk factor for sporadic Alzheimer's disease (AD). While APOE4 is strongly associated with amyloid-beta (Aβ), its relationship with tau accumulation is less understood. Studies evaluating the role of APOE4 on tau accumulation showed conflicting results, particularly regarding the independence of these associations from Aβ load.

Background/objectives: X-linked hypophosphataemic rickets (XLH) represents the most frequent type of rickets from genetic origin, it is caused by mutations on the gene. The main clinical manifestations are short stature and bone deformities. Phenotype variation is observed at the intrafamily and interfamily level.
