  • 4. INTRODUCTION
    The cytogeneticsis the study of chromosomes in number and in structure,
    The main technique for humancytogeneticsstudyisrepresented by fluorescence in situ hybridization (FISH), whichisconsidered a technique thatrevolutionized the chromosome analysis in humancytogenetics and emerges as a promising technique in the fieldclinicalgenetics, clinicaloncology and clinicalresearchs.
  • 5. The investigation is to ascertain whether the suppression of chromosome 9p in clear cell renal carcinoma (ccRCC) predicts worse disease-specific survival (DSS).
  • 6. suppression of chromosome 9
    Chromosome 9p.
    • When you suppress the chromosome 9p it stops removing large tumors, creating a greater likelihood of having a high tumor classification.

  • 7. Deletion of chromosome 9p.
    Deletion of chromosome 9p confers a worse prognosis independent in patients with localized disease ccRCC, and most notably, in patients with localized mass, small kidney
  • 8. Prevention of carcinoma
    Histological appearance of renal cell carcinoma
    the identification of patients with 9p deletions improve risk stratification and help select appropriate patients for surveillance protocols or aggressive treatment.

  • 9. Observation .
    I thinkthatthisstudy has greatclinical application, sinceitallows to determinewhich patients are athighrisk of developingrenal cancer and throughthis to preventdecreasing the morbidity and mortality.
  • 10. long arm of chromosome 20 is an abnormality of acute myeloid leukemia (AML)and myelodysplastic(MDS) syndrome and is presumed to cause the loss of a tumor suppressor gene in the 20q12.
  • 11. Tumor suppressor gene
    Additional copies of chromosome 20 may generate an amplification of the regions of the chromosome where the gene suppressor as in a translocation.
  • 12. Activation de an oncogen.
    By RT-PCR has shown a correlation between amplification and increased expression of gen.
    Localized and high-level amplification of the 250 kb region common is a test for the activation of an oncogene in this region in these cases of MDS and AML.
  • 13. Tumor suppressor gene
    • 20q11.21 amplified cases tended to have a high proportion of erythroblasts in the bone, with two cases diagnosed as erythroleukemia
    Suppressor gene inactivation

  • 14. Observation
    frommy point of viewthis investigation allows for a more information about acute myeloidleukemiaresulting in a better perspective on this and be able to actat the site of the errorcausing a possible diagnosis.
  • 15. Citogenetyc
    Cytogeneticis the branch of geneticthatstudies the diseases of chromosomalinheritanc.
  • 16. Cytogeneticabnormalities
    The cytogeneticallowsdetermining the type of chromosomalabnormalityis a diagnostic toolthatallows confirmation of the diagnosis of suchdiseases and also the propergeneticcounseling of patients and theirfamilies ;.
  • 17. Cytogenetic and cancer
    The cytogenetic in the cancer represents and avvantadge for a rapidprevention of manydiseases, including cancer recurrentrecurring chromosome in certain malignanttumors
  • 18. Role of cytogenetics
    the cytogenetics plays an important role in these two aforementioned pathologies such as leukemia, renal carinomamieloidy and enabling you to identify genetically affected site and provides a pattern in their evolution.
