PKU- phenylketonuria, genetic disorder characterized by the body’s inability to use the essential amino acid (phenylalanine) -an example of an inborn error of metabolism, the body is unable to metabolize phenylalanine -although the condition is genetically determined, it doesn’t manifest itself until an infant consumes phenylalanine, that is why it is prenatal AND perinatal -PKU may be controlled by adherence to a strict diet -prevalent among Scandinavians -the TORCH group consists of infections that may pass the placental barrier and cause severe disabilities, because the infections come from outside the fetus- they are environmental causes of retardation -the TORCH group consists of these infections: -Toxoplasmosis is a single-cell organism that is contracted thru contact with cat feces or undercooked meat -it can be avoided with thorough hand washing and by eating only adequately cooked meat -Syphilis (“other”) is a sexually-transmitted disease (STD) -can be remedied with wide-spectrum antibiotics

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
