Role in Disease
Mutations in the gene lead to hyperuricemia:
- Some men have partial (up to 20% less activity of the enzyme) HGPRT deficiency that causes high levels of uric acid in the blood, which leads to the development of gouty arthritis and the formation of uric acid stones in the urinary tract. This condition has been named the Kelley-Seegmiller syndrome.
- Lesch-Nyhan syndrome is due to HPRT mutations resulting in extremely ineffective enzyme activity.
- Some mutations have been linked to gout, the risk of which is increased in hyperuricemia.

Famous quotes containing the words role in, role and/or disease:
“Friends serve central functions for children that parents do not, and they play a critical role in shaping children’s social skills and their sense of identity. . . . The difference between a child with close friendships and a child who wants to make friends but is unable to can be the difference between a child who is happy and a child who is distressed in one large area of life.”
—Zick Rubin (20th century)
“The addition of a helpless, needy infant to a couple’s life limits freedom of movement, changes role expectancies, places physical demands on parents, and restricts spontaneity.”
—Jerrold Lee Shapiro (20th century)
“And this disease that was Swann’s love had so multiplied, it was so intimately tied to all of Swann’s habits, to all his acts, to his thoughts, to his health, to his sleep, to his life, even to what he desired for his afterlife, his love was so much a part of him that it could not be extracted from him without destroying him entirely: as is said in surgery, his love was inoperable.”
—Marcel Proust (1871–1922)
