TP53 deletion is a recurring abnormality in AML, CLL, MDS, and plasma cell dyscrasia disorders including Plasma Cell Myeloma.

TP53 deletion is a poor cytogenetic risk factor across several disorders including AML, CLL, MDS and myeloma.

This test can be ordered individually or as part of a Plasma Cell Dyscrasia FISH Panel (See the individual panel test for more details).
