“Aiden is one of the happiest kids you’ll ever meet,” says his Mom, Bonnie Procyshyn. “My eldest son is easy going and has the greatest smile. Preferring people to toys, Aiden loves to connect and interact with others.”
When Aiden was born, Bonnie and her husband, Andrei, were told that his newborn screening showed some abnormal results. Despite not receiving a diagnosis for many months, the family was connected with a metabolic specialist. Aiden underwent many tests, but, as is so often the case, none were conclusive.
When Aiden was 6 months old, Bonnie started noticing developmental delays. He wasn’t hitting basic milestones, like sitting up. At nine months, he had no interest in solid foods and was hospitalized for concerns about his failure to thrive.
Aiden started having seizures around his first birthday. This precipitated a switch in focus from a metabolic care team to a neurological one. Whole Genome Sequencing (WGS) was ordered shortly thereafter. The results indicated that Aiden had Leigh’sSyndrome, a debilitating mitochondrial disease. He was 15 months old at this time. Bonnie and Andrei were told it was unlikely their son would see his fifth birthday.
“Aiden’s cells can’t generate enough energy for him to function the way he’d like to,” says Bonnie.
This means frequent naps, sensitivity to heat, and delays in movement and speech. Aiden’s mito is de novo, which means it is the result of a random genetic mutation that could not have been predicted. 97% of his cells are affected.
