Is Essential Tremor Genetic?
Essential tremor is a nervous system disorder that causes involuntary, rhythmic shaking. It most commonly affects the hands but can also involve the head, voice, and other body parts.
Affects ~1 in 25 adults over 40.
Genetic Factors Behind Essential Tremor
Research has identified multiple genetic variants that influence a person's susceptibility to Essential Tremor. While no single gene determines whether someone will develop this condition, specific variants can increase or decrease risk. Key genes studied in relation to Essential Tremor include:
LINGO1SLC1A2FUSTENM4LINGO1LINGO1 has been associated with essential tremor in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
SLC1A2SLC1A2 has been associated with essential tremor in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
FUSFUS has been associated with essential tremor in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
TENM4TENM4 has been associated with essential tremor in genetic studies; as with most common variants, its individual effect is modest and works alongside many other genetic and non-genetic factors.
How GenomeInsight Analyzes Your Risk
GenomeInsight examines your raw DNA data from services like 23andMe, AncestryDNA, or whole-genome sequencing (VCF files) to identify genetic variants associated with Essential Tremor. The analysis is performed entirely in your browser, meaning your genetic data never leaves your device.
For each relevant variant, GenomeInsight reports your genotype, the associated risk allele, the odds ratio from published research, and your overall risk profile compared to the general population. Results are presented with easy-to-understand risk visualizations and percentile rankings.
Genetic risk is only one piece of the puzzle. Lifestyle, diet, environment, and family history all contribute to overall risk. GenomeInsight's analysis is for informational and educational purposes and is not a medical diagnosis.
Understanding Your Essential Tremor Results
After uploading your DNA file, you will receive a detailed health risk report covering 52 conditions, including Essential Tremor. For each condition, GenomeInsight analyzes multiple SNPs (single nucleotide polymorphisms) and calculates a combined risk assessment.
Your results will show whether you carry risk-increasing or protective alleles in genes like LINGO1, SLC1A2, FUS, and TENM4. Risk levels range from "Below Average" to "Significantly Increased," with population percentile comparisons to contextualize your results.
Frequently Asked Questions About Essential Tremor
Which genes are linked to Essential Tremor?
The variants most consistently associated with Essential Tremor lie in or near LINGO1, SLC1A2, FUS, TENM4. Each variant shifts risk modestly on its own; the report combines all of them into an overall genetic risk estimate compared with the reference population.
If I carry risk variants, will I develop Essential Tremor?
Not necessarily. A genetic predisposition means your probability is higher than average — it is not a diagnosis. Lifestyle, environment, age and chance all contribute, and most people with elevated genetic risk never develop the condition. Conversely, low genetic risk is not a guarantee of protection.
What DNA data do I need for this analysis?
A raw-data file from 23andMe, AncestryDNA, MyHeritage or a whole-genome VCF covers the markers used in this analysis. Upload takes place entirely in your browser — your file is never transmitted to or stored on any server.
