Likewise, what is Trisomy 12 called?
Chromosome 12, trisomy 12p, is an extremely rare chromosomal disorder in which a portion of the short arm of the 12th chromosome (12p) appears three times (trisomy) rather than twice in cells of the body.
Secondly, what is the life expectancy of a person with CLL? The prognosis of patients with CLL varies widely at diagnosis. Some patients die rapidly, within 2-3 years of diagnosis, because of complications from CLL. Most patients live 5-10 years, with an initial course that is relatively benign but followed by a terminal, progressive, and resistant phase lasting 1-2 years.
Also know, can you live with Trisomy 12?
Trisomy 12 is the second most frequent aberration detected by fluorescence in situ hybridization at the time of diagnosis (10–25%), and it confers an intermediate prognostic risk, with a median time to first treatment of 33 months and a median overall survival of 114 months.
Is there a trisomy 12?
Trisomy of the short arm of chromosome 12 is a rare chromosomal anomaly, with an estimated incidence of 1/50,000 births. It may present as a pure trisomy (complete or incomplete), as mosaic trisomy, or with other chromosomal abnormalities.

Chronic lymphocytic leukemia (CLL) can rarely be cured. Still, most people live with the disease for many years. Some people with CLL can live for years without treatment, but over time, most will need to be treated.How do you know if CLL is getting worse?
Another symptom of CLL progression is extreme fatigue and shortness of breath while doing your normal day-to-day activities. This is due to fewer healthy red blood cells and more cancer cells accumulating in your body.What should be avoided in CLL?
