Clinics and Pathology

Disease	Chronic myelogenous leukemia (CML) in blast crisis; the t(X;21) may be therapy related.
Epidemiology	Only one case to date, a female patient aged 23 years (Jeandidier et al., 2006).

Cytogenetics

Additional anomalies

t(9;22)(q34;q11), +8, i(17q).

Genes involved and Proteins

Note	The partner of RUNX1 is unknown.

Gene Name	RUNX1 (runt-related transcription factor 1 (acute myeloid leukemia 1; aml1 oncogene))
Location	21q22.12
Protein	Contains a Runt domain and, in the C-term, a transactivation domain; forms heterodimers; widely expressed; nuclear localisation; transcription factor (activator) for various hematopoietic-specific genes.

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity: you are welcome to submit a paper to our new Case Report section.
