t(8;19) (p11;q13) is a variant of t(8;16) (p11;p13)

Additional anomalies

Two cases :
  • 46,XX,t(8;19)(p11;q13.2)/idem,-16,-16q+
  • 46,XX, t(8;19)(p11;q13) sole anomaly
  • Genes Involved and Proteins

    Gene name
    KAT6A (MYST histone acetyltransferase (monocytic leukemia) 3
    MOZ contains a LAP (Leukemia associated protein) zinc finger domain, a HAT domain (Histone acetyltransferase) and a acidic domain. Detection by FISH : YAC 176C9.
    Protein description
    Monocytic leukemia zinc finger protein
    2004 amino acids and 225 kDa nuclear protein, with 2 LAP/PHD-type zinc fingers.
    MOZ is a histone acetyltransferase (HAT) and the founding member of the MYST family of HATs, a family that includes proteins involved in cell cycle regulation, chromatin remodeling and dosage compensation.
    MOZ plays an important role during hematopoiesis with his transcriptional coregulator activity.
    Gene name
    The partner of MOZ is unknown in this translocation.

    Result of the Chromosomal Anomaly


    In the t(8 ;19) the fusion protein is unknown.

    Two distinct clinical syndromes have been associated with the 8p11-p12 region :
  • Stem-cell myeloproliferative disorder with FGFR1 rearrangement
  • AML M4 or M5 erythrophagocytosis-associated with MOZ rearrangement.
  • This t(8;19)(p11;q13) with MOZ involvement should not be confused with the t(8;19)(p11;q13) with FGFR1 involvement found in the stem-cell myeloproliferative disorder.

    The partners of 8p11 are 8q13, 14q11, 16p13, 19q13, 22q13 and 3q27, 17q12 in a complexe translocation t(3;8;17)(q27;p11;q12).
