Is Ménière’s Disease Genetic?
Ménière’s disease appears to have a genetic component, so there may be a gene variant(s) connected to the regulation of endolymph fluid.
A 2026 study by Divya Chari, M.D., a 2024–2025 Emerging Research Grants scientist, suggests that variants of a single gene may alter inner ear development decades before symptoms begin. (Chari’s 2024 ERG grant was generously funded by an anonymous donor and renewed for a second year in 2025, generously funded by Karen I. Coley.)
Recent research by Penn Medicine also links developmental genetics to adult vestibular conditions.
At the 2025 Ménière’s Disease Symposium, Jose Antonio Lopez-Escamez, M.D., Ph.D., of University of Sydney, Australia, shared:
• Ménière’s disease can be seen as not a single disease but as multiple subtypes, including three immune response-related subgroups (autoimmune, autoinflammatory, and IgE-associated) that can be identified through measuring cytokines and IgE in blood tests, while approximately 40% of patients may have a genetic origin with normal immune responses.
• Genetic research has identified about 20 genes associated with familial Ménière’s disease, with the three most common being OTOG (encoding otogelin), MYO7A (encoding myosin), and TECTA (encoding alpha-tectorin), and a newly discovered gene GJD3 (encoding Connexin 31.9), with most genetic cases involving the stereocilia and tectorial membrane.
• These findings suggest Ménière’s disease often results from a combination of genetic predisposition (a “fragile ear”) plus environmental triggers like noise exposure, with approximately 9 percent of European cases being familial, and an estimated 28 percent of sporadic cases potentially having genetic origins as well.
At the same symposium, Andreas Eckhard, M.D., of Harvard Medical School/Mass Eye and Ear, shared:
• Evidence that endolymphatic hydrops may be a compensatory cell response to inner ear injury rather than a pure pathology challenges the traditional view of Ménière’s disease as primarily a fluid pressure disorder.
• Research shows that the endolymphatic sac, which makes up about a third to half of the inner ear’s epithelial surface, is consistently damaged in Ménière’s disease patients, and this damage represents a major injury to the inner ear.
• This suggests a new model where Ménière’s disease follows a pattern of maladaptive progression similar to chronic kidney disease: with initial injury, compensatory mechanisms (including cell proliferation in hydropic membranes), a phase of fluctuating function, and eventual burnout.
The discoveries of Dr. Echkard’s team (which includes Drs. Chari and Juliano) are summarized in the Fall 2025 issue of Harvard Otolaryngology Magazine and quoted below:
New insights reveal that Ménière’s disease is driven by abnormal cell overgrowth in the inner ear, not simply by fluid pressure as long believed.
This harmful cell overgrowth appears to be the inner ear’s misguided attempt to repair itself after it initially sustained damage to the endolymphatic sac.
Different underlying problems damage the endolymphatic sac in different patients, and researchers have defined the first disease subtype using imaging and genetics—opening the door to more precise diagnosis and personalized, targeted therapies.
