DNA/RNA

Description	spans over 50 kb; 9 exons
Transcription	alternative splicing including/excluding exon 2

Protein

Description	385 amino acids; 47 kDa ; a DNA binding domain and 2 repeat motifs
Localisation	nucleus; associated with the chromatin and with the nuclear matrix
Function	binds and activates human immunodeficiency virus integrase; member of the SWI/SNF complex, thought to facilitate the transcriptional activation of inducible genes through the remodelling of the chromatin; could be involved in the chromatin organization associated with the nuclear matrix attachment; could also have a role in the cell cycle control, through binding to P105-Rb
Homology	with SNF5 (yeast transcription factor)

Mutations

Germinal	found in the rhabdoid tumor predisposition syndrome
Somatic	mutation and allele loss events in sporadic rhabdoid tumors are consistent with the two-hit model of Knutson; deletion of the entire gene on one allele (sometimes due to translocations involving 22q11), and mutation (frameshift mutations, widely dispersed through the entire gene and leading to stop codons) on the other allele

Implicated in

Note

Entity	rhabdoid tumor
Disease	tumor of uncertain origin, occuring in early childhood
Prognosis	highly aggressive; 80% mortality rate
Cytogenetics	normal karyotype or t(Var; 22)(-;q11.2)
Hybrid/Mutated Gene	no hybrid gene but inactivation of both alleles


Entity	rhabdoid tumor predisposition syndrome
Hybrid/Mutated Gene	germline mutation on one allele, predisposing to a rabdoid tumor (and perhaps to tumors of the central nervous system) when the other allele is also inactivated
