Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

Movement Disorders, Volume 41, Issue 9, Page 2476-2489, September 2026.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.

Rare‐Variant Burden across Lysosomal Genes Implicates Sialylation and Ganglioside Metabolism in Parkinson's Disease

Movement Disorders, Volume 41, Issue 9, Page 2349-2356, September 2026.
Abstract Background Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses ...

Integrative Multi‐Omics Profiling Reveals Age‐Associated Genomic and Tumor Microenvironmental Heterogeneity in Colorectal Cancer

MedComm – Oncology, Volume 5, Issue 3, September 2026.
Integrated multi‐omics analysis defines an age‐resolved molecular–immune framework in colorectal cancer. Early‐onset tumors show reduced APC/KRAS alterations, frequent SMAD4 disruption, enriched PTPRK–RSPO3 fusions, and increased CD4+ memory T cells and mast cells with greater checkpoint responsiveness.

Sporadic hemiplegic migraine and epilepsy associated with CACNA1A gene mutation.

, 2010
Familial hemiplegic migraine (FHM) is a clinically and genetically heterogeneous disease most commonly linked to CACNA1A gene mutation. Epilepsy rarely occurs in FHM and is seen predominantly with specific CACNA1A gene mutations.
