In a ground-breaking discovery that could help patients with unexplained liver and kidney problems, scientists have identified a new disease.Experts at Newcastle University, UK, have established the inherited condition, called TULP3-related ciliopathy that causes kidney and liver failure in children and adults.There are numerous reasons for kidney and liver organ failure, which if left untreated is life-threatening, but often patients do not get a precise diagnosis which can make their best course of treatment unclear.Faulty gene the catalystResearch, published in the American Journal of Human Genetics, has revealed that a faulty gene is the catalyst for increased fibrosis in the liver and kidney, often resulting in the need for a transplant.Professor John Sayer, Deputy Dean of Clinical Medicine at Newcastle University, said: "Our finding has a huge implication for better diagnosis and management of kidney and liver disease in some patients."What we are now able to do is give some patients a precise diagnosis, which allows their treatment to be tailored to their needs for the best possible outcome."In the study, experts reviewed clinical symptoms, took liver biopsies and genetic sequencing from scores of patients, where a total of 15 patients from eight families were identified as having this new disease.Urine samples from these patients were used to grow cells in a laboratory and then investigated to determine the precise defect causing TULP3-related ciliopathy.Over half the patients in the study had a liver or kidney transplant as their condition had deteriorated significantly. In these patients the original cause for their organ failure was unknown until the study.Professor Sayer, who is a consultant nephrologist at Newcastle upon Tyne Hospitals NHS Foundation Trust, said: "We were surprised at how many patients we were able to identify with TULP3-related ciliopathy and this would suggest that the condition is prevalent within those with liver and kidney failure."We hope to provide a proper diagnosis for many more families in the future. This work is a reminder that it is always worth investigating the underlying reasons for kidney or liver failure to get to the bottom of the condition."Finding a genetic cause of liver or kidney failure has huge implications for other family members, especially if they are wishing to donate a kidney to the patient."The work, co-funded by Kidney Research UK and the Northern Counties Kidney Research Fund, was possible through the Genomics England 100,000 Genomes project, where Professor Sayer has been instrumental in the local success of this project.The Newcastle experts will now work with cell lines taken from patients to study more in detail the disease process and to test potential treatments for TULP3-related ciliopathy.Patient case studyLiver transplant patient Linda Turnbull is leading a full and active life since she received her new organ almost 30 years ago.The barrister, from Stocksfield, Northumberland, UK, is part of the Newcastle University study and was one of the 15 patients identified as having the new condition, TULP3-related ciliopathy.Linda, who is in her 60s, was always an unwell child and things became worse when she started vomiting blood where, at the age of 11, tests diagnosed her with liver failure.She was treated successfully, but gradually her liver failed completely resulting in the need for a transplant in 1994. More recently she was noted to also have kidney failure.Linda provided urine samples for the study so her cells could be grown in the laboratory for the new disease to be understood more. Her involvement has helped patients locally, nationally and internationally.She said: "It is brilliant to finally have an answer to my life-long questions: Why has this happened to me and why do I have this condition."It's fantastic that this research has been led in Newcastle and it means that people in the future will have information regarding their condition and how best to treat it."( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
