Review on i(X)(p10) in male patients

Clinics and Pathology


Extremely rarely i(X)(p10) occurs in male patients; only three cases has been reported in lymphoid malignancies, including ALL (Martineau et al, 1996; Gerr et al., 2010) and Follicular lymphoma (Donti et al., 1988).

Phenotype stem cell origin

Trilineage immunophenotype of lymphoblasts in one patient (Gerr et al, 2010); CD19+,CD10- in another one (Martineau et al, 1996).

Survival was 12 months in one case (Gerr et al, 2010).

Result of the Chromosomal Anomaly


The major consequence of this abnormality is loss of several genes on Xq and gain of several genes on Xp, that leads to genetic imbalance.
