A thickening of the connective tissue under the skin of the palm that gradually bends the fingers. A genome-wide study of it found nine risk loci, and six of them independently point at the same signalling pathway — the kind of convergence that makes a genetic finding a mechanism rather than a list.
Dupuytren's disease is a slowly progressive thickening and tightening of the fascia — the connective tissue layer just under the skin of the palm — which gradually pulls one or more fingers, most often the ring and little fingers, into a permanently bent position that cannot be straightened. It is particularly common in people of Northern European descent, more common in men, and its cause has never been reduced to one thing.
The study behind this page is a genome-wide association study of 960 Dutch cases and 3,117 controls, replicated in a further 1,365 cases and 8,445 controls from Germany, the United Kingdom and the Netherlands. It found nine loci reaching genome-wide significance — a substantial number for a single study of a single disease — and its headline finding is not any one of them individually. It is that six of the nine sit in genes belonging to one signalling system: Wnt signalling, a pathway that governs how cells decide their identity and how tissue organises itself, both during development and during repair.
Those six are WNT4, SFRP4, WNT2, RSPO2, SULF1 and WNT7B — three Wnt ligands themselves, a Wnt inhibitor, a Wnt-pathway modulator, and an enzyme that shapes the extracellular signalling environment Wnt proteins act in. Six independent genome-wide hits landing in one pathway, rather than being scattered across unrelated biology, is a much stronger form of evidence than any single locus on its own: it is very unlikely to happen by chance, and it points at a specific mechanism — tissue believing it needs to repair or remodel itself when it does not — rather than leaving the biology unexplained.
This page's variant, rs11672517, sits near DUXA, one of the other three loci — not part of the Wnt-pathway group the study's own conclusion is built around. It is named here as what it is: one of the nine genome-wide hits, without folding it into a pathway story it is not part of.
Diagnosis is made by physical examination — feeling the thickened cords and nodules in the palm and observing the finger contracture — and does not require imaging or a genotype in typical cases. Treatment ranges from watchful waiting in mild cases to procedures that break or remove the thickened tissue, chosen based on how much the contracture is interfering with hand function.
What this page cannot do. This variant shifts risk by a fraction and does not predict who will develop Dupuytren's disease or how severe it will become. A thickening lump or cord in the palm, or a finger that is starting to pull toward the palm and will not fully straighten, is what should prompt a hand specialist's evaluation — not a genotype.
A study that found one gene associated with a disease has found one clue. A study that finds six independent genes converging on one pathway has found something closer to a mechanism, because six separate genome-wide signals landing in the same biological system by chance is extremely unlikely. That is what elevates this paper above a list of positions: Wnt signalling's role in tissue remodelling gives a plausible account of why fascia would thicken and contract, in a way that a single isolated locus could not.
What a 23andMe/AncestryDNA export or raw VCF can and can't tell you about Dupuytren's Disease comes down to these specific, well-studied positions — not a diagnosis.

No. This variant shifts risk by a fraction and does not predict an individual outcome. A thickened cord or nodule in the palm, or a finger that will not fully straighten, is what should prompt an evaluation by a hand specialist.
Because six independent genome-wide signals landing in the same biological system by chance is extremely unlikely. It is much stronger evidence for a real mechanism — in this case, Wnt signalling's role in how tissue remodels itself — than any single locus considered alone.
No, and the page says so directly. It is one of the study's nine genome-wide loci, near DUXA, but it is not one of the six in the Wnt-signalling group the paper's main conclusion is built around.
That is a reasonable question the genetics raises, but this study is genetic, not a drug trial, and it does not establish that targeting the pathway would help. Whether it would is a separate, unanswered question.
