The Multiple Sclerosis Severity Allele rs10191329^A and Cognitive Function: A UK Biobank Study

Area of Science:

• Neurogenetics
• Cognitive Neuroscience

Background:

• A genome-wide association study identified the genetic variant rs10191329A associated with Multiple Sclerosis severity and long-term disability.
• Brain resilience was implicated as a key factor influencing outcomes in Multiple Sclerosis.

Purpose of the Study:

• To investigate the potential influence of the rs10191329A genetic variant on cognitive function.
• To explore the association of rs10191329A with cognition in healthy controls and patients with neurological diseases.

Main Methods:

• Utilized the UK Biobank dataset for the study.
• Assessed cognitive performance using tests for reaction time, fluid intelligence, and prospective memory.

Main Results:

• Observed a weak but consistent association between the rs10191329A variant and poorer cognitive function in healthy controls.
• Identified similar, albeit non-significant, trends of impaired cognition associated with rs10191329A in Multiple Sclerosis, Parkinson's disease, and dementia cohorts.

Conclusions:

• The findings support the hypothesis that the rs10191329A genetic variant may impact cognitive function.
• Results suggest rs10191329A could influence neurological disease outcomes, potentially through effects on brain health and resilience.
