We are a family of 5 – our oldest son Owen  is healthy and happy. Soon after our daughter Alyssa was born, we noticed she wasn’t meeting her developmental milestones. Approximately 3 years later, she was diagnosed with Methylmalonic Semialdehyde Dehydrogenase Deficiency through the genetics/metabolic team at CHEO. We are grateful that we were able to receive a diagnosis. Later, our youngest son Connor was born. There was a 1 in 4 chance that Connor could be affected with the same disease. Connor is a carrier of the disease but is not affected by it. We are truly grateful to CHEO for their support and for all the services that they provide for our daughter.
