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
