Scientists are studying how two genes work together to cause frontotemporal dementia, a type of brain disease that affects thinking and behavior. One gene called GRN normally makes a protein that protects brain cells, but when it's broken, people can develop dementia. Another gene called TMEM106B can either increase or decrease the risk of getting sick. This research helps explain why some people with the broken GRN gene stay healthy their whole lives while others get dementia.
WHY IT MATTERSIf you or a family member carries a GRN mutation, understanding how TMEM106B variants modify your risk could eventually help doctors predict who will develop frontotemporal dementia and when, potentially enabling earlier monitoring or future preventive treatments.

Scientists discovered that fasting may help reverse heart damage caused by a specific genetic mutation in the PLN gene called R14del. This mutation causes a common type of inherited heart disease where abnormal protein clumps build up in heart cells. The research shows that fasting activates the cell's cleanup system (lysosomes) to remove these harmful clumps and restore heart function.
WHY IT MATTERSIf confirmed in human studies, fasting could offer PLN R14del cardiomyopathy patients a non-drug intervention to potentially reverse heart damage, though this is currently only demonstrated in laboratory research and requires clinical validation.

Researchers found that a protein called DDR2 is overactive in Alzheimer's disease and may be blocking the brain's natural cleaning system. They developed an antibody (a type of immune protein) that can cross into the brain and reduce DDR2 levels, which in early studies helped restore the brain's ability to clear out harmful waste products and improved Alzheimer's symptoms in animal models.
WHY IT MATTERSThis research identifies a new therapeutic target for Alzheimer's disease that works through a different mechanism than current treatments, potentially offering hope for patients whose disease progresses despite existing amyloid-targeting therapies.
ResearchBIORXIVApr 14
Scientists created a new AI system called CoNVict that helps doctors figure out which genetic changes are actually causing rare diseases. Copy number variants (CNVs) are sections of DNA that are duplicated or missing, and they can cause genetic disorders, but it's hard to know which ones matter. This new tool uses artificial intelligence to automatically score and rank these genetic changes so doctors can focus on the ones most likely to be causing a patient's symptoms.
WHY IT MATTERSIf your child has unexplained developmental delays or birth defects and genetic testing found copy number variants, this AI tool could help doctors identify which variant is actually responsible for your child's condition, potentially speeding up diagnosis.

Researchers studied how much money families and the healthcare system spend on KCNT1-related disorders, a rare genetic brain condition that causes severe seizures starting in early childhood. The study used information from both families caring for patients and medical records to understand the true financial costs. This is important because there are currently no approved treatments that can change the course of the disease, so families face lifelong expensive care.
WHY IT MATTERSIf you have a child with KCNT1-related epilepsy, this research documents the financial burden your family faces and provides evidence that could support insurance coverage decisions and funding for new treatments.

Researchers studied the genes of people with pulmonary fibrosis (a disease where lung tissue becomes scarred and stiff) to find rare genetic changes that might cause the disease. They found that problems in genes related to how cells maintain their structure may play an important role in developing pulmonary fibrosis. This discovery could help doctors better understand why some people develop this serious lung condition.
WHY IT MATTERSIf you or a family member has pulmonary fibrosis, this research could eventually help explain your genetic risk and lead to new treatments targeting the cellular structures that are damaged in this disease.
ResearchBIORXIVApr 5
Scientists created a new tool called Gene Portals that helps doctors understand whether genetic changes cause rare diseases. Instead of searching through many different websites and databases, doctors can now use one central location that combines patient information, lab test results, and genetic data all in one place. This makes it easier and faster to figure out if a genetic mutation is actually responsible for a patient's rare disease.
WHY IT MATTERSPatients with rare genetic diseases may finally get faster and more accurate diagnoses because doctors will have a standardized way to interpret genetic test results, reducing the chance of misdiagnosis or missed diagnoses.
ResearchBIORXIVApr 4
Researchers developed a new test called targeted long-read sequencing that can better identify which genetic changes affect how genes are read and used in cells. This test is more accurate than older methods at finding these changes in patients with neurological disorders, and it's faster and cheaper than previous approaches.
WHY IT MATTERSIf you have a neurological disorder where genetic testing hasn't found a clear diagnosis, this method could help doctors identify the actual genetic cause by better detecting splicing variants that standard tests miss.
ResearchBIORXIVApr 3
Scientists created a new computer tool called FA-NIVA that helps doctors find genetic mistakes in Fanconi anemia patients more accurately. Fanconi anemia is a rare inherited blood disorder caused by mistakes in specific genes. This new tool uses advanced DNA sequencing technology that reads longer pieces of DNA, making it easier to spot all types of genetic errors, including big deletions and insertions that older methods sometimes miss.
WHY IT MATTERSThis tool could help doctors diagnose Fanconi anemia more accurately and completely by detecting genetic variants that standard testing methods currently miss, potentially leading to faster diagnosis and better understanding of individual patient mutations.

Researchers discovered that mutations in a gene called THAP12 cause a severe type of childhood epilepsy called developmental and epileptic encephalopathy. Two siblings with this condition had two broken copies of the THAP12 gene (one from each parent), which stopped the gene from making enough of its protein. This finding helps explain why some children develop severe seizures early in life and could lead to better diagnosis and treatment options.
WHY IT MATTERSFamilies with children diagnosed with infantile spasms or Lennox-Gastaut syndrome now have a new genetic cause to test for, which could explain their child's condition and guide future treatment decisions.
