| SMARCB1 | |
|---|---|
| Immunostain in short | |
 INI1-ve in AT/RT. | |
| Abbreviation | SMARCB1, BAF47 |
| Normal staining pattern | nuclear staining |
| Positive | any healthy tissue |
| Negative | AT/RT, renal rhabdoid tumour, extrarenal malignant rhabdoid tumour, atypical teratoid/rhabdoid tumour, epithelioid sarcoma |
SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1, commonly abbreviated SMARCB1 (or INI1 or BAF47), is a diagnostic immunostain, because nuclear staining is lost in some specific types of cancer shown below.
Negative
- Epithelioid sarcoma.[1]
- Extrarenal malignant rhabdoid tumour.[2]
- Renal rhabdoid tumour.
- SMARCB1 (INI-1)-deficient carcinomas of the sinonasal tract.[3]
- Atypical teratoid/rhabdoid tumour.[4]
