  6. 6. Changes in conditions of Chr-17 <ul><li>ACUTE PROMYELOCYTIC LEUKEMIA </li></ul><ul><li> caused by a rearrangement (translocation) of genetic material between chromosomes 15 and 17 [t(15;17)] </li></ul><ul><li> fuses part of the PML gene from chromosome 15 with part of the RARA gene from chromosome 17. </li></ul><ul><li>somatic mutation  not inherited. </li></ul><ul><li>The t(15;17) translocation is called a balanced reciprocal translocation </li></ul><ul><li>The protein produced from this fused gene is known as PML-RARα. </li></ul>
  7. 7. Scheme of acute promyelocytic leukemia <ul><li>PML gene (chr-15) >< RARA gene (chr-17) </li></ul><ul><li>[t(15;17) balanced reciprocal translocation] </li></ul><ul><li>PML-RARα </li></ul>RARα a protein  tumor suppressor blood cells are stuck at the promyelocyte stage, and they proliferate abnormally. Excess promyelocytes accumulate in the bone marrow and normal white blood cells cannot form, leading to acute promyelocytic leukemia.
  8. 8. <ul><li>Chromosome 18 </li></ul><ul><ul><li>one copy inherited from each parent, form one of the pairs. </li></ul></ul><ul><ul><li>Chromosome 18 spans about 76 million DNA building blocks (base pairs) and represents approximately 2.7 percent of the total DNA in cells. </li></ul></ul>CHARACTERISTICS
  9. 9. Cont’d Normal chromosome 18
  10. 10. Major conditions changes in chr-18 18 p- There is a missing piece from the short arm of chromosome 18. 18q- There is a missing piece from the long arm of chromosome 18.  If the missing piece is close to the centromere, it is called proximal 18q-.  If the missing piece is close to the end of the chromosome, it is called distal 18q-.
  11. 11. Major conditions changes in chr-18 Ring 18 One of the copies of chromosome 18 forms a ring, and material is lost from both the long and short arm. Tetrasomy 18p An extra chromosome is present. This chromosome is made up of two copies of the short arm of chromosome 18.
  12. 12. Major conditions changes in chr-18 Trisomy 18 There are three copies instead of the usual two.
