Use [https://www.genenames.org/ <u>HUGO-approved gene names and symbols</u>] (italicized when appropriate), [https://varnomen.hgvs.org/ HGVS-based nomenclature for variants], as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column to a table, click nearby within the table and select the > symbol that appears to be given options. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged. Additional instructions below in italicized blue text should not be included in the final page content.

chr7:1- 159,335,973 [hg38]

 

|Yes

|No

 

Presence of monosomy 7 (or 7q deletion) is sufficient for a diagnosis of AML with MDS-related changes when there is ≥20% blasts and no prior therapy (add reference).  Monosomy 7/7q deletion is associated with a poor prognosis in AML (add reference).

 

chr8:1-145,138,636 [hg38]

 

|No

|No

 

Common recurrent secondary finding for t(8;21) (add reference).

==Characteristic Chromosomal Patterns==

 

!Diagnostic Significance (Yes, No or Unknown)

!Prognostic Significance (Yes, No or Unknown)

!Therapeutic Significance (Yes, No or Unknown)

!Notes

|Yes

|No

|No

 

See chromosomal rearrangements table as this pattern is due to an unbalanced derivative translocation associated with oligodendroglioma (add reference).
