This Concept Map, created with IHMC CmapTools, has information related to: PKU, Pregnant mother is a homozygous recessive for PKU, PKU patients should avoid foods including red meat, fish, eggs, milk, cheese, Pregnant mother has high serum phenylalanine which likely affects developing fetus, serum phenylalanine elevated in pt's with PKU, CNS function inhibition of NMDA receptors, PKU caused by defective gene, autosomal recessive reproduction produces 1 % chance of PKU in developing fetus, tyrosine important for CNS function, PKU reproduction produces 1 % chance of PKU in developing fetus, Father has allele frequncy of 2% chance of being PKU carrier, Pregnant mother produces pt with Father, developing fetus compromised by maternal serum phenylalanine. Theories of mechanism include CNS devolopment, proteins and NT deficiency of leads to decreased levels of dopamine and serotonin, CNS devolopment abnormal because of alterations in molecular markers, CNS devolopment abnormal because of inhibition of alpha TOCOPHEROLQUINONE, Pregnant mother educated about controlling serum phenylalanine, phenylalanine converted by PAH to make tyrosine, PKU displays inheritance pattern of autosomal recessive, PKU caused by defective co factor, red meat, fish, eggs, milk, cheese which contains high levels of phenylalanine
