Africa-Press – Mozambique. <\/strong><\/span>Scientists say in some cases it is diagnosis and not the cure that plays a crucial role \u2013 patients can spend years suffering from certain symptoms and still be unaware of what ailment they have. The new method is expected to rectify this problem and help treat diseases in their early stages.<\/p>\n

A simple DNA test may make a breakthrough in diagnosing genetic and neurological diseases, claims a group of international scientists. According to the findings of their study, which will be published in The Lancet next month, whole genome sequencing (WGS) can accurately detect the most common neurological disorders.<\/p>\n

As the name implies WGS analyses the entire genomic DNA sequence of an individual and looks at possible mutations and health indicators. The method developed by the researchers uses an algorithm that compares elements in the genome sequence of a healthy person with those affected by so-called repeat expansion disorders, caused by expansion in DNA repeats. Scientists say the advantage of their method is that they can test \u201cmultiple variants at the same time\u201d.<\/p>\n

The method was used on 11,631 undiagnosed people with symptoms associated with repeat expansion disorders and resulted in 68 diagnoses. Among the patients who benefited were children \u2013 a teenager with dementia and a 10-year-old girl with an intellectual disability. Scientists say both individuals were likely to have remained undiagnosed because they didn\u2019t have a history of neurological diseases in the family.<\/p>\n

Eileen Flynn, a patient at The Ataxia Centre at University College London Hospitals, was diagnosed with Friedreich\u2019s ataxia, a genetic disease that causes difficulty walking, a loss of sensation in the arms and legs, and impairs speech.<\/p>\n
