Pearl S. Buck and Phenylketonuria (PKU)

Abstract

In 1921, Pearl S. Buck gave birth to a daughter, Carol, who became severely retarded and was eventually institutionalized at the Vineland Training School in New Jersey. To help pay for her daughter's care, Buck wrote The Good Earth in 1931, and then other novels and biographies about her life in China, for which she was awarded the Nobel and Pulitzer Prizes, and honored around the world. Years later, she published The Child Who Never Grew, a short piece about her daughter's retardation that also revealed her desperate search for answers and good clinical care. Asbjørn Følling distinguished phenylketonuria (PKU) from other forms of childhood retardation in the mid-1930s, and new assays and biochemical findings eventually led to ways to circumvent the devastating effects of PKU. But for Carol Buck, these advances came too late. It was not until the 1960s that physicians confirmed that her severe retardation was caused by PKU.

Genetics of Phenylketonuria: Then and Now

“…Carol, who became severely retarded and was institutionalized in a special school in New Jersey, was diagnosed with PKU in the 1960s, far too late [Finger and Christ, ]. This was probably the first description of a child with PKU.…”
