Is Ehlers-Danlos Syndrome Genetic?
Is Ehlers-Danlos Syndrome hereditary? Here's what the research says about inherited risk.
- Heritability
- ~90%
- Inheritance
- autosomal-dominant
- Key genes

Ehlers-Danlos syndrome is a group of connective tissue disorders characterised by joint hypermobility and skin fragility. Different subtypes are caused by different gene mutations.
How Genetic Is Ehlers-Danlos Syndrome?
Ehlers-Danlos Syndrome has a strong genetic basis. Research estimates heritability at approximately 90%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Ehlers-Danlos Syndrome: COL5A1,COL5A2,COL3A1,TNXB. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Ehlers-Danlos Syndrome?
Yes — family history is one of the strongest predictors of Ehlers-Danlos Syndrome. If a first-degree relative (parent, sibling, or child) has been diagnosed, your own risk may be significantly elevated. Discussing your family history with a healthcare provider or genetic counsellor is strongly recommended.
Frequently Asked Questions
Is Ehlers-Danlos Syndrome genetic?
This condition has a strong genetic basis. Studies suggest heritability of approximately 90%. Key genes involved include COL5A1,COL5A2,COL3A1,TNXB.
Can a DNA test reveal my risk of Ehlers-Danlos Syndrome?
Yes — DNA tests such as CircleDNA's Premium Test include reports on Ehlers-Danlos Syndrome risk based on your genetic variants.
Does family history matter for Ehlers-Danlos Syndrome?
Yes — family history is one of the strongest predictors of Ehlers-Danlos Syndrome. If a first-degree relative has been diagnosed, your own risk may be significantly elevated.
Is Ehlers-Danlos Syndrome hereditary, meaning it's passed directly from parent to child?
Ehlers-Danlos Syndrome follows a autosomal-dominant inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
