Abstract

We have previously shown correction of X-linked severe combined immunodeficiency [SCID-X1, also known as γ chain (γc) deficiency] in 9 out of 10 patients by retrovirus-mediated γc gene transfer into autologous CD34 bone marrow cells. However, almost 3 years after gene therapy, uncontrolled exponential clonal proliferation of mature T cells (with γδ+ or αβ+ T cell receptors) has occurred in the two youngest patients. Both patients' clones showed retrovirus vector integration in proximity to the LMO2 proto-oncogene promoter, leading to aberrant transcription and expression of LMO2 . Thus, retrovirus vector insertion can trigger deregulated premalignant cell proliferation with unexpected frequency, most likely driven by retrovirus enhancer activity on the LMO2 gene promoter.

  • SCID-X1 patients who received HSCs transduced with murine leukaemia virus developed abnormal T cell proliferation due to insertion of a retroviral vector near the LMO2 proto-oncogene.

    “For example, SCID-X1 patients who received HSCs transduced with murine leukaemia virus (MLV) developed abnormal T cell proliferation due to the insertion of a retroviral vector near the LMO2 proto-oncogene [123,124].”
  • Integration of proviral DNA can disrupt or enhance expression of host genes, resulting in altered and sometimes fatal outcomes.

    “Equally consequential is the integration of the proviral DNA for the host, since it can either disrupt or enhance the expression of the host genes, resulting in altered and sometimes even fatal outcomes (Hacein-Bey-Abina et al. 2003, Bushman 2007, Montini et al. 2009, Desfarges and Ciuffi 2012).”
  • Lentiviral vectors are considered safer than gamma-retroviral vectors in terms of their semi-random integration patterns, as gene integration does not preferentially occur in start regions of active genes.

    “Lentiviral vectors are considered safer than gamma-retroviral vectors in terms of their semi-random integration patterns, as gene integration does not preferentially occur in start regions of active genes (93-95).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
