HPPD is also directly linked to Type III tyrosinemia When the active HPPD enzyme concentration is low in the human body, it results in high levels of tyrosine concentration in the blood, which can cause mild mental retardation at birth, and degradation in vision as a patient grows older.

Famous quotes containing the words disease and/or relevance:
“The fantasies inspired by TB in the last century, by cancer now, are responses to a disease thought to be intractable and capriciousthat is, a disease not understoodin an era in which medicines central premise is that all diseases can be cured.”
—Susan Sontag (b. 1933)
“... whatever men do or know or experience can make sense only to the extent that it can be spoken about. There may be truths beyond speech, and they may be of great relevance to man in the singular, that is, to man in so far as he is not a political being, whatever else he may be. Men in the plural, that is, men in so far as they live and move and act in this world, can experience meaningfulness only because they can talk with and make sense to each other and to themselves.”
—Hannah Arendt (19061975)
