From Uncertainty to Pathogenicity: Resolving a CSF1R Variant of Uncertain Significance Using Long‐Read Transcriptomics

Movement Disorders, EarlyView.
Abstract Background CSF1R‐related disorder (CSF1R‐RD) is a severe autosomal dominant leukoencephalopathy characterized by progressive cognitive, neuropsychiatric, and motor decline. Although genetic testing is widely available, numerous likely pathogenic variants in CSF1R frequently remain classified as variants of uncertain significance (VUS ...

1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...
