New York, Oct 12 || Motor delay and low muscle tone are common signs of an underlying genetic diagnosis in children with neurodevelopment disorders, scientists have found.
The researchers from University of California-Los Angeles (UCLA) Health Sciences aimed to research which factors in this subset of children indicated the need of a genetic test.
“With genetic testing, a diagnostic result can have benefits on medical care, but we don’t have established clinical guidelines on the early neuro-developmental signs that classify who gets genetic testing or not”, said Dr Julian Martinez, medical geneticist at UCLA Health.
Knowing the early neurodevelopment symptoms that signal for a genetic diagnosis can benefit both a patient’s family and doctor.
A patient’s family can advocate to see a geneticist, and a geneticist provides testing that can potentially give a positive genetic diagnosis, which can help with monitoring the onset of other medical concerns or provide an opportunity to start a treatment for the specific genetic condition, if one is available.
The study, published in Genetics in Medicine, reviewed medical charts from 316 patients seen at the UCLA Care And Research In NeuroGenetics (CARING) Clinic from 2014-2019.
The patients were categorised based on their genetic testing results, then the researchers documented clinical factors that differentiated patients with and without a genetic diagnosis.
The researchers found that, overall, patients with a genetic diagnosis were more likely to be female and receive early intervention services for a history of motor delay, low muscle tone, and/or congenital heart disease.
