Q

Associated with Down Syndrome

Peripheral blood and bone marrow have increased lymphoblasts

A

ALL
(T-cell)
Acute Lymphoblastic Leukemia/Lymphoma

AML both are associated with Down, but
only ALL has lymphoblast in BM, not just peripheral

20
Q

TRAP +

A

Hairy Cell Leukemia

“It’s a TRAP Harry!”

21
Q

What is the function of BCL2

A

To stabilize mitochondrial membrane thus inhibiting cytochrome C from inducing apoptosis of tumor cell

22
Q

On what chromosome is BCL2 supposed to be

A

Starts on 18
but
moves/translocates to another chromosome with a constitutively on locus like Chrm 14 Ig Heavy chain locus

23
Q

t(12,21)

A

ALL

Acute Lymphoblastic Leukemia/Lymphoma

24
Q

Richter Transformation

A

CLL (SLL) transfroms to DLBCL

Diffuse Large B Cell Lymphoma

25
Q

Most common adult Leukemia

A

Chronic Lymphocytic Leukemia

26
Q

The abnormal PML/RARα fusion protein blocks differentiation of myeloid precursors in what diseases

A

APL
Acute Promyelocytic Leukemia

from t(15;17)

27
Q

What induces differentiation of promyelocytes

A

all-trans retinoic acid (vitaminA)
and
arsenic

28
Q

t(9,22) leads to what abnormality

not the disease

A

BCR-ABL hybrid

B-cell receptor (BCR) fuzes with Tyrosine Kinase Protein (ABL) causing TK signaling to be always on.

The Philadelphia (Ph) chromosome is an abbreviated chromosome 22 that was shortchanged in a reciprocal exchange of material with chromosome 9.

29

A

Myeloid

30
