- Gene affected:
- ARID1A (AT-Rich Interaction Domain 1A)
- Clinical significance
- ARID1A controls gene transcription and is recurrently mutated in Follicular lymphoma, but mutation is also seen in other lymphoma types. Mutation disrupts a range of functional processes, and may particularly affect DNA repair, sensitising cells to DNA damage during therapy. The link to prognosis remains unclear at present.
Function of gene
This gene encodes a member of the SWI/SNF family, responsible for regulation of gene transcription by altering chromatin structure around specific genes. ARID1A is frequently disrupted a range of cancers and developmental disorders resulting in loss of expression. The precise role in malignancy is unclear, but it may act as a tumour suppressor.
