Grenada 2010 Sickle Cell Association of Grenada

On 25 June 2010 The Sickle Cell Association of Grenada (SCAG) gathered at the Sauteurs Grenada Catholic Cemetery to lay a wreath and to unveil a plaque in memory of Dr Walter Clement Noel, who became the first recorded case of sickle cell disorder in history. In 1910, Dr James B Herrick publish an article reporting the case of an anaemic student from Grenada with peculiar sickle-shaped red blood cell. Walter C. Noel was born in Grenada on 21 June 1884, he successfully completed in dentistry studies in Chicago and returned to Grenada to do his practice; he died on 3 May 1916 at the age of 32, nine years after his return. Today sickle cell anaemia is the world's largest genetic disorder. The gene defect causing this disease is a mutation of a single nucleotide (single-nucleotide polymorphism - SNP) (A to T) of the ß-globin gene, which results in glutamic acid being substituted by valine (mutation of a single nucleotide, from a GAG to GTG codon). 2 souvenir sheets were released on 9 December 2010 to acknowledge the Sickle Cell Association of Grenada and to commemorate the centennial of the reporting of the first sickle cell case; the designs of the stamps include ribbons and flowers which were part of the wreath laid at the grave of Dr Walter Clement Noel.
