Additional information

Germline and sporadic mutations in SMARCB1/INI1 predispose patients to rhabdoid tumours. These are highly malignant, particularly aggressive tumours of infancy and early childhood, approximately 35% have been demonstrated to be of germline orign. Testing for mutations is by direct sequencing and comprise mainly missiense and frameshift mutatios which result in stop codons. Loss of heterozygoisty is detected using MLPA (see separate entry)
