Is Multiple Sclerosis Hereditary?
Multiple sclerosis (MS) is not directly inherited in a simple pattern, but having a close relative with MS increases risk. A daughter of a mother with MS has a higher lifetime risk compared with the general population, though the absolute risk remains relatively low.
Can MS Be Passed From Mother to Daughter?
Research shows that first-degree relatives, including mothers and daughters, share a modestly elevated risk. Factors such as genetic susceptibility, shared environment, and immune system differences may contribute. No single gene causes MS, and inheritance is complex.
What Increases Risk Beyond Family History?
Other influences include low vitamin D levels, certain infections, smoking, and geographic location. While a mother with MS may raise a daughter's awareness, lifestyle factors and regular medical care also matter. Early diagnosis and treatment can help manage the disease.
