Piper Monroe Martin, 20, of Allen, Texas passed away, May 31, 2004, after a long battle with a rare metabolic disorder known as Hartnups, at Medical Center in Plano, Texas. He was born July 2, 1983. He spent the first 17 years of his life in Tyler, Texas, where he was lovingly cared for by his family, the First Baptist Church of Tyler and his school, The Wayne Boshears School of Exceptional Children. In 2001 he and his family moved to Allen, Texas to be near a larger medical community. Although Mr. Martin lost his ability to talk and then walk at an early age and his mental prowess waned with each passing year, his short life proved invaluable to medical science. Serving as a study model for the then incurable disease called Hartnups for a Texas funded research group at Herman Hospital in Houston, and infant diagnosis procedure, now known as “The Piper Test” was developed. This test and the subsequent treatment administered within the first six week of life can often eradicate the deadly syndrome, Hartnups Type II, from the effected individual. Martin’s clinical study was published in the New England Journal of Medicine. He is survived by his father and mother, Danny and Livonna Martin of Allen, Texas; one brother, Garrett Lynn Martin of Allen; his grandmother, Marie Martin of Nacogdoches, Texas; grandparents, Rev. and Mrs. Thomas B. Guinn of Chattanooga, Tennessee; numerous aunts, uncles, cousins, and a long line of loving nurses and care-givers. Family and friends visitation will be at Turrentine-Jackson-Morrow Funeral Home at 2525 Central Expressway North at Ridgeview Drive in Allen, Texas, Wednesday, June 2, from 7:00-9:00 PM.
