How do rare genetic disorders affect vitamin B12 metabolism and embryonic development?Vitamin B12 plays a crucial role in our growth and development.Without it, our bodies cannot produce healthy blood cells or maintain a functioning nervous system.For most people, a balanced diet provides enough vitamin B12 to stay healthy, but for some, rare genetic disorders mean their bodies cannot use this vital vitamin properly.Dr Ross Poch from Baylor College of Medicine in Houston, Texas, USA, uses mouse models to study these disorders, understand how they disrupt embryonic brain development and explore new ways of treating them.
