Parents call for heel prick testing after son, 7, dies from degenerative disease
Families Demand Newborn Screening Following Tragic Loss of Seven-Year-Old
The parents of a seven-year-old boy who passed away from a rare degenerative condition are scheduled to meet with lawmakers in Westminster on Tuesday. Their mission is to advocate for mandatory newborn screening, a measure they argue could have preserved their son’s life.
Teddy Johnson, hailing from Portadown, was born with Metachromatic Leukodystrophy (MLD), a rare metabolic disorder characterized by the progressive deterioration of physical and cognitive abilities. His mother, Jemma, revealed that Teddy was diagnosed at 18 months of age, a point at which treatment was no longer viable because symptoms had already manifested.
MLD occurs in approximately one in 40,000 births. While it can be managed if identified early in infancy, the Department for Health and Social Care stated that any expansion of screening programs "must be guided by science."
Jemma described Teddy as a perfectly healthy infant who exhibited no early warning signs of the disease. "He was your very normal, cheeky little monkey," she recalled. "He hit all of his milestones and was walking from 11 months old. He was perfect in every way."
However, the situation shifted around his 17th month when he began walking with a limp—a stark contrast to his previous mobility. Initially, Jemma and her husband, Marvin, did not view it as a major concern. But after four weeks, the limp had worsened significantly, prompting them to seek medical advice.
The referral to a neurologist resulted in a devastating diagnosis. "Their world fell apart," Jemma said, recalling the moment they were told their son likely would not survive past the age of four. Following the diagnosis, Teddy began to lose every skill he had acquired by 18 months.
Although the couple was informed of a potential treatment available in Italy, it was restricted to children who had not yet shown symptoms. Consequently, Teddy’s condition deteriorated rapidly. Little over a year after his diagnosis, he had lost most of his physical functions. He became unable to speak or move, experienced constant pain, and his body grew rigid. He required feeding through a gastric peg.
"The hardest part for me was him losing his talking," Jemma explained. "To not hear him call mum or dad or his older sister's name was incredibly difficult."
Dedicating their lives to his care, Jemma and Marvin abandoned their careers. "We gave up our careers as we were told his decline would be very fast, and this was the best thing we could have done as we were able to dedicate our full attention to him," she said. "We protected him through covid and to us he was royalty in our house. Life has revolved around him completely for the last six years."
Teddy passed away on April 16. "Teddy has left a massive void in our lives," his mother stated.
Earlier this year, the UK National Screening Committee (NSC) advised against including MLD in the current panel of 10 rare conditions screened via the newborn 'heel prick' test. The committee cited uncertainties regarding the accuracy of screening tests, the establishment of suitable test cut-off levels, and whether early detection following screening actually improves long-term health outcomes.
Despite this, the Johnsons are traveling to London to present their case to politicians, including Sharon Hodgson, the UK Parliamentary Under-Secretary of State for Public Health and Prevention. Marvin emphasized their goal to inform health leaders that Teddy’s death was preventable.
"We want to educate health leaders that Teddy's death could have been avoided and he could have lived a normal life if his rare condition had been picked up on the heel prick test," Marvin said. "We are campaigning for other parents to give them the opportunity to save their children. It's very important that we make change. Children are dying because of it."
The family faces further anxiety as their daughter, Jean, was identified as a carrier of the MLD gene, posing a risk to any future offspring.
In the wake of Teddy’s death, Carla Lockhart, the DUP MP for Upper Bann, urged the Prime Minister to reconsider early testing protocols. In response, Sir Keir Starmer committed to re-evaluating the inclusion of MLD in newborn screening programs.
Highlighting the UK’s lag in this area compared to other nations, Lockhart remarked, "We are so far behind other countries with this. Parents are being robbed of their children." She noted that some researchers estimate the cost of such a program would amount to...
