Background: The kinesin light-chain 1 genetic variants G56836C, A185C, and C406T were earlier found to amplify the development of leukoaraiosis in hypertensive smokers. These 3 variants were presumed to affect the function of the mitochondria, thereby giving rise to sensitivity to a chronic ischemic state. We have now extended our investigations to examine how the above genetic variants affect the occurrence of ischemic stroke.
Methods: Genetic and clinical data on 650 ischemic stroke and 340 neuroimaging alteration-free subjects were analyzed. Univariate and logistic regression approaches were used.
Results: None of the above genetic variants proved to be risk factors of ischemic stroke, either alone or in combination with other clinical factors.
Conclusion: The examined 3 genetic variants seem to influence the responses of the glial cells to a slight chronic hypoxia state, rather than the mechanisms resulting in cerebral infarcts themselves.

Genetic Predisposition to Low-Density Lipoprotein Cholesterol and Incident Type 2 Diabetes.
JAMA Cardiol
January 2025
Program of Medical and Population Genetics, Broad Institute of MIT (Massachusetts Institute of Technology) and Harvard, Cambridge, Massachusetts.
Importance: Treatment to lower high levels of low-density lipoprotein cholesterol (LDL-C) reduces incident coronary artery disease (CAD) risk but modestly increases the risk for incident type 2 diabetes (T2D). The extent to which genetic factors across the cholesterol spectrum are associated with incident T2D is not well understood.
Objective: To investigate the association of genetic predisposition to increased LDL-C levels with incident T2D risk.
KMT2C Polymorphism in Familial Hypospadias.
Indian J Pediatr
January 2025
Department of Pediatric Surgery, All India Institute of Medical Sciences, New Delhi, 110029, India.
Hypospadias, a common congenital anomaly of male genitalia, shows significant heritability and familial recurrence, particularly in consanguineous families. This study explored the role of KMT2C polymorphisms in a Yemeni family with two affected siblings. Comprehensive analysis identified 475 unique SNPs in KMT2C, with 59 shared between parents, suggesting common ancestry.

Center for Immunity and Immunotherapies, Seattle Children's Research Institute, Seattle, WA, USA.
Reduced function or hypomorphic variants in recombination-activating genes (RAG) 1 or 2 result in a broad clinical phenotype including common variable immunodeficiency (CVID) and even adult-onset disease. Milder RAG variants are less characterized. Here we describe the longitudinal course of a milder combined RAG deficiency in 3 of 7 siblings sharing the same RAG2 mutations over a 50-year study.

J Neurol
January 2025
Department of Neurology and Neurosciences, Donostia University Hospital, Biogipuzkoa Health Research Institute, Donostia-San Sebastián, Spain.
Background: Alpha-actinin-2, a protein with high expression in cardiac and skeletal muscle, is located in the Z-disc and plays a key role in sarcomere stability. Mutations in ACTN2 have been associated with both hypertrophic and dilated cardiomyopathy and, more recently, with skeletal myopathy.
Methods: Genetic, clinical, and muscle imaging data were collected from 37 patients with an autosomal dominant ACTN2 myopathy belonging to 11 families from Spain and Belgium.
Association of IL6 Gene Polymorphisms and Neurological Disorders: Insights from Integrated Bioinformatics and Meta-Analysis.
Neuromolecular Med
January 2025
Department of Genetic Engineering & Biotechnology, University of Dhaka, Dhaka, Bangladesh.
Interleukin 6 (IL6) is an inflammatory biomarker linked to central and peripheral nervous system diseases. This study combined bioinformatics and statistical meta-analysis to explore potential associations between IL6 gene variants (rs1800795, rs1800796, and rs1800797) and neurological disorders (NDs) and brain cancer. The meta-analysis was conducted on substantial case-control datasets and revealed a significant correlation between IL6 SNPs (rs1800795 and rs1800796) with overall NDs (p-value < 0.
