  4. 4.  Caused by a genetic mutation on 22nd chromosome that results in the deletion of a portion of it Autosomal dominant immunodeficiency Results in poor development of several body systems The underlying cause is a shrunken or missing thymus gland
  5. 5. 2.  Contains 500 to 800 genes  Genes codes for the development of the thymus gland are missing  Region known as 22q11.2  Contains 30-40 genes
  6. 6. 3.
  7. 7.  Specialization in the 4. immune system Most active as a child and begins to atrophy in puberty as a result of increase in sex hormones Produce T- Lymphocytes  These are your white blood cells
  8. 8.  Shrinkage of parathyroid glands- results in hyposecretion of PTH (parathyroid hormone) Messes up regulation of calcium and phosphorus Bluish skin (poor circulation of oxygen) – cyanosis Delayed speech development Cleft palate can usually be surgically repaired Spasms of the mouth and throat (tetany) Frequent infections due to decline in immune system Low set ears, wide set eyes, or a narrow groove in the upper lip
  9. 9. Example of Cleft Palate Example of Cyanosis5. 6.
  10. 10.  Not an actual syndrome, rather a type of disorder Cardiac effects Abnormal facial features Thymic hypoplasia Cleft palate Hypocalcaemia 22 –refers to the chromosome
  11. 11.  DSG occurs in one infant per 4,000 born It is a lifelong condition that affects mostly children and infants Approximately one-third of affected adults experience recurring infections 7.
  12. 12.  Pitcher for the Chicago Cubs In 2009 Dempster and wife Jenny gave birth to daughter Riley Dempster who was born with Digeorge Syndrome. Dr.’s focus on Riley’s feeding and swallowing Tracheostomy and Passy-muir Valve Created “Dempster Family Foundation” for kids with Digeorge syndrome. Ryan was nominated twice for the Roberto Clemente award for his community service.
