Q

Which translocation occurs in cml

A

T 9 22occurs in the cml
Abl gene in the 9 th chromosome and bcl gene in the 22 chromosome fuses to form abl bcc gene
With high tyrosine activity
Auto activation occurs and cell proliferation occurs independently of growth factors

What is primary pcv and secondary pcv

A

Primary pcv lo erythropoietin levels are low
In the secondary they are high occurs in high altitude places
And in smokers and copd patients
