Day 3 of #HD2026 put HTT under the microscope. Researchers shared new insights into HTT1a, next-generation HTT-lowering approaches, somatic expansion, brain circuitry, and why boosting healthy HTT might help. Read our roundup here.Read more

⏱️ 23 min read | Day 2 of #HD2026 brought us updates on the mechanics of somatic instability, new ways to track HD in people, AI tools to help drive research forward, and developments in our understanding of the HTT protein. Catch up right here.Read more

⏱️ 28 min read | Day1 of HD2026 is a wrap! From what human brains can teach us about HD, to HTT1a, somatic CAG expansion and the normal biology of HTT, today’s talks spanned the spectrum from fundamental biology to potential treatments.Read more

Clinical trial data can drive discovery long after a study ends. Prilenia donated placebo-arm data from 2 HD clinical trials to CHDI, a valuable resource for researchers to better understand placebo effects, HD progression and future trial design.Read more

⏱️10min read | Roche's decision to stop development of 2 HTT-lowering programmes is disappointing, but the story doesn't end there. Years of research answered some key questions, raised many new ones, and will inform the next generation of HD trials.Read more

⏱️ 8 min read | July was a hard month for Huntington's disease research, with Roche ending two HD programs. But the month also brought promising new tools, a new player in somatic expansion, and important work on eating and self-awareness in HD.Read more

⏱️10 min read | Four years after announcing positive results in their trial of ANX005 (tanruprubart) for HD, Annexon has formally published the results. It’s safe, hits its target, and may have helped some participants – so what’s the holdup?Read more

⏱️8 min read | Scientists have known that MutLβ is linked to repeat expansion but not exactly how. A study reveals that the MutLβ protein complex is a main player supporting and interacting with key DNA repair proteins to drive DNA repeat expansions.Read more

⏱️8 min read | Scientists screened over a trillion tiny ring-shaped protein fragments to find ones that can grab onto the huntingtin. They captured huntingtin straight out of cells and discovered it’s almost always paired with a partner called HAP40.Read more

⏱️6 min read | A new study suggests that reduced awareness of symptoms, known as anosognosia, may appear even in the earliest stages of HD. The findings highlight that understanding symptom progression requires more than one perspective.Read more

⏱️8 min read | People with Huntington’s disease commonly experience unintended weight loss. A recent article identified the challenges around HD’s impact on eating and weight maintenance, and explored how families and professionals navigate them.Read more

⏱️ 10 min read | Roche announced it is stopping development of two of its huntingtin-lowering ASO drugs, tominersen and RG6496. This marks a disappointing end to an important chapter in HD clinical research. Read more

⏱️8 min read | For the past 20 years, PET tracers have been a game-changer for Alzheimer’s disease, making it possible to see amyloid plaques in the brain without invasive procedures. So what about Huntington's?Read more

⏱️ 6 min read | New 12-month data from Skyhawk's SKY-0515 is in and all four measures that make up the cUHDRS are at or above baseline, beating expected natural decline. Plus, a first look at expanding US trial sites.Read more

⏱️ 10 min read | From the clinic, we heard from uniQure about their recent FDA meeting, a stem cell trial dosed its first participant, and Skyhawk shared data on SKY-0515. In the lab, the science of slowing HD at the DNA level keeps building.Read more

⏱️6 min read | PROTACs act like a precision pruning tool, trimming away toxic huntingtin protein while leaving the healthy form intact. In cells and HD mice, this targeted clean-up improved health and slowed disease features.Read more

⏱️13 min read | Australia just made history by banning life insurers from using genetic testing against you. But for HD families in other countries, the laws meant to protect haven't kept pace with the science. Let’s break down what you need to know.Read more

⏱️ 9 min read | After a turbulent past year, uniQure have shared encouraging news that the FDA has agreed their Phase I/II study data can serve as the basis for an application that could lead to the approval of AMT-130 in the US.Read more

A new clinical trial for HD is underway. The first participant has been dosed in REGEN4HD, a study testing whether transplanting neural stem cells is safe as a potential treatment for HD.Read more

⏱️ 9 min read | Huntington’s disease affects more than movement: it also has a major impact on mental health. Researchers explore why psychological care matters and how it needs to be adapted across each stage of HD.Read more

⏱️ 7 min read | Your body assembles DNA like a team of workers who set and bond a pattern of tiles. A recent study shows that one special assistant might slow somatic CAG expansion and delaying HD onset.Read more

⏱️7 min read | In 2025, you helped us reach 329,000 people with independent, unbiased HD research news. Our 2025 Annual Report is here. Take a look at what we built together, and consider helping us keep going.Read more

One year into treatment, SKY-0515 continues to lower huntingtin and shows encouraging trends with signs and symptoms of HD. A larger trial is enrolling to determine whether the drug truly slows HD progressionRead more

⏱️8 min read | May 2026: 2 year data from the votoplam trial suggests disease progression may slow; AMT-130 heads to the UK for regulatory review; pigs reveal immune cells invading the HD brain; and new science zooms in on toxic huntingtin fragments.Read more

⏱️7 min read | In a recent paper, scientists targeted a small, harmful piece of the huntingtin message (HTT1a) in HD mice. This reduced toxic protein clumps and delayed genetic changes, more than targeting full length HTT.Read more

⏱️ 5 min read | A recent study suggests that strengthening the brain's own clean-up system could slow Huntington’s disease.Read more

⏱️ 5 min read | Prilenia's application for European approval of pridopidine was quietly withdrawn 6 months ago, in November 2025, after the EMA had already recommended refusing the drug. Here's what happened, and why you're only hearing about it now.Read more

⏱️7 min read | A recent study in pigs suggests the HD brain could be under attack from the body's own immune system. The results reveal that invading cytotoxic T cells might contribute to neurodegeneration in HD, suggesting a new therapeutic pathway.Read more
