Term Description

This test measures the valine level in children who have been diagnosed with maple syrup urine disease and are on a therapeutic diet for their condition. Dried blood spot specimens are sent to the lab for monitoring tests periodically. The valine level is used in combination with leucine and isoleucine levels to monitor the patient's progress.

Part Descriptions

LP15946-4   Valine
Valine, one of the 20 proteinogenic amino acids, is nutritionally essential. It is named after the plant valerian. Foods that are good sources of valine include cottage cheese, fish, poultry, peanuts, sesame seeds, and lentils. In sickle cell disease, the replacement of an A by T in the beta chain gene of hemoglobin changes the codon GAG (for glutamic acid) to GTG (which encodes valine). Thus valine, a hydrophic amnio acid, replaces glutamic acid, a hydrophilic amino acid, causing hemoglobin to not fold correctly. It is also a precursor in the penicillin biosynthetic pathway.
