Gene Information

human ... SMARCB1(6598)

General description

INI-1, also known as SMARCB1, is one of the core subunit proteins of the ATP-dependent SWI/SNF chromatin remodeling complex. It is involved in chromatin remodeling and transcriptional regulation and functions as a tumor suppressor. Nuclear INI-1 expression is seen in virtually all normal human tissues and most malignancies but the INI-1 gene is often mutated or deleted in malignant rhabdoid tumors (MRT), including those arising in the central nervous system, leading to a lack of INI-1 expression.

Primary extrarenal rhabdoid tumors (RT) are now recognized as a specific entity in pediatric oncological pathology practice. We present an unusual case of a small cell myxoid variant of a thoracic RT in an infant and highlight the importance of

Immunohistochemical lack of nuclear INI1 protein expression has been recently described as characteristic finding in atypical teratoid/rhabdoid tumors (AT/RTs), and has been suggested as useful marker to distinguish AT/RTs from other malignant pediatric central nervous system (CNS) tumors. In this

Rhabdoid tumours (RTs) are rare but highly aggressive tumours of childhood. Their rarity and their miscellaneous locations make the diagnosis particularly challenging for pathologists. Central nervous system and peripheral RTs have been associated with biallelic inactivation of the hSNF5/INI1/SMARCB1 (hSNF5/INI1)

Multiple primary malignant neoplasms (MPMN) are defined as two or more primary malignancies diagnosed in an individual. There is no association between these cancers, which can be classified into synchronous and heterochronous cancers depending on the time of diagnosis. The
