what enzyme is deficient in galactosemia Class 9 galactose metabolism

Galactosemia is a rare genetic disorder that affects the body’s ability to break down and utilize galactose, a sugar found in milk and other dairy products. It is caused by a deficiency of enzymes needed to process galactose, resulting in a buildup of toxic substances in the body. This condition can have serious consequences if not managed properly.

Understanding Galactosemia

Galactosemia is typically detected soon after birth through newborn screening tests. Early detection is crucial as immediate dietary intervention is necessary to prevent complications. Infants with galactosemia need to be put on a lactose-free diet, which means avoiding breastfeeding and any formula or food containing lactose.

Living with galactosemia can be challenging, but with proper management and support, individuals can lead healthy lives. It is important for individuals with galactosemia to work closely with healthcare professionals, including geneticists, dietitians, and other specialists, to ensure they are receiving the necessary care and support.

Common Enzyme Deficiency

Galactosemia is primarily caused by a deficiency of the enzyme galactose-1-phosphate uridylyltransferase (GALT), which is responsible for breaking down galactose in the body. Without this enzyme, galactose cannot be converted into glucose, leading to its accumulation in the body.

This deficiency is inherited in an autosomal recessive manner, meaning both parents must carry the defective gene for their child to be affected. If both parents are carriers, each pregnancy has a 25% chance of resulting in a child with galactosemia.

Managing Galactosemia

The primary treatment for galactosemia is a strict lactose-free diet. This means avoiding all sources of lactose, including milk, cheese, yogurt, and any food products made with these ingredients. Individuals with galactosemia must rely on lactose-free alternatives, such as soy milk or rice milk, to meet their nutritional needs.

In addition to dietary restrictions, individuals with galactosemia may require additional supplementation to ensure they are receiving all necessary nutrients. This may include calcium and vitamin D, as these nutrients are often found in high quantities in dairy products.

Regular monitoring and follow-up with healthcare professionals are essential for individuals with galactosemia. Close attention must be paid to their growth and development, as well as any potential long-term complications. With proper management, individuals with galactosemia can lead healthy and fulfilling lives.

In conclusion, galactosemia is a rare genetic disorder that requires meticulous dietary management. By following a lactose-free diet and receiving appropriate medical care, individuals with galactosemia can successfully navigate the challenges associated with this condition. Early detection, intervention, and ongoing support are crucial for managing galactosemia and ensuring the best possible outcomes for those affected.
