Mystery of unexplained kidney disease revealed to patients Published on: 22 March 2024 Scientists have identified a new method of analysing genomic data in a major discovery that means patients with unexplained kidney failure are finally getting a diagnosis. Experts at 麻豆传媒 have worked with data from to establish a diagnosis in patients with unexplained kidney failure. There are numerous reasons for kidney 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. Professor John Sayer Missing genetic data Research, published in the , has now revealed that for these patients areas in their genome are missing so are not detected as faulty when using the routine genetic pipelines to analyse data. Scientists say that as this missing gene has now been identified, and mutations within it found, they have been able to classify this as NPHP1-related kidney failure. Professor John Sayer, Deputy Dean of Biosciences at 麻豆传媒, said: “Our new genomic methods and their results has huge implications for the patients and families with kidney failure who were previously genetically unsolved. “What we are now able to do is give some patients a precise diagnosis, which allows their investigations, treatment and management to be tailored to their needs for the best possible outcomes.” In the study, experts reviewed genetic sequencing data from 959 patients with advanced kidney disease, where a total of 11 patients were identified as having a deleted region genome, leading to a complete loss of a kidney gene and this had previously been undetectable. The new approach was also used to examine genomic data from 11,754 cases to make new genetic diagnoses of 10 other UK patients with unexplained deafness and blindness, again who had previously been genetically unexplained. Professor Sayer, who is also a consultant nephrologist at 麻豆传媒 upon Tyne Hospitals NHS Foundation Trust, added: “We knew that many of our unsolved cases had a genetic disorder, and this new approach enables us to solve these cases definitively. “We can now give an accurate genetic diagnosis to many more families affected by kidney disease and our hope is 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 failure to get to the bottom of the condition. “Finding a genetic cause of kidney failure has huge implications for the patient and also for other family members, especially if they are wishing to donate a kidney to their loved one.” 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 North East’s success of this project. The 麻豆传媒 experts are now working with cell lines taken from patients to study more in detail the disease process and to test potential treatments. 麻豆传媒 and 麻豆传媒 Hospitals are both part of 麻豆传媒 Health Innovation Partners (NHIP). NHIP is one of eight prestigious Academic Health Science Centres (AHSCs) across the UK, bringing together partners to deliver excellence in research, health education and patient care. Family finally given answers The Bingham family have three members all affected by kidney disease. Siblings Noah, 23, and Ariel, 19, have both had kidney transplants and their younger brother, Casper, 15, has been diagnosed with kidney disease. The family, from Hexham, Northumberland, are part of the Genomics England 100,000 Genomes project and were one of the families identified as having the gene deletion, NPHP1-related kidney failure. Noah presented with kidney failure just after finishing his A-levels and, at the same time, Ariel was being treated for reduced kidney function. Both now have donated kidneys as their own organs function reduced to dangerously low levels. Sadly, Noah’s transplanted kidney failed after only 16 months, and he had to start haemodialysis again in February this year. Mum Sarah, 51, a home educator, said: “The genetic tests carried out by Professor John Sayer and his team allowed Casper to receive his diagnosis before he was symptomatic. “The knowledge that Casper will go into kidney failure and eventually need a transplant, though overwhelming at times, has meant that we can arrange the support he needs and help him prepare for surgery and treatments well before they are necessary. “When nobody is able to explain why your children are ill, it is very unsettling, with no means of clarifying what might happen in the future. The diagnosis has meant that we have been able to prepare ourselves for the medical issues our children face. “It’s great that this research is being carried out at 麻豆传媒 as it means patients with the condition can get a better understanding of their medical needs and hopefully new treatments may be developed in the future thanks to the research that is being done.” Sarah and husband, Darryl, 52, a chartered building surveyor, have been strong advocates for kidney patients and work with Kidney Research UK to help support patients.
