(A) Lysosomal storage diseases (LSD) are a group of rare metabolic disorders that require extremely expensive enzyme replacement therapy. This solution can cost $300,000-$500,000 a year for children and even more than 16 for adults. Enzymes are required to break down substances in the body’s cells. LSD sufferers’ enzymes are either 17 or low in numbers. As a result, substances build up in the cells, and the cells must then be replaced.18 , mammalian cell cultures are the only suitable replacement, and they don’t come cheap.Luckily, those born with metabolic disorders can now breathe a sigh of relief. Scientists have found a new method of producing the 19 enzymes from corn. This process should cut costs significantly, thereby making treatment more affordable and 20 premature deaths of sufferers. Mass-producing enzymes from corn is still a long way off, but the new treatment, when readily available, will offer sufferers a level playing field in overall healthcare costs.
