| Gene | ARID1A |
| Variant | Q456* |
| Impact List | nonsense |
| Protein Effect | loss of function |
| Gene Variant Descriptions | ARID1A Q456* results in a premature truncation of the Arid1a protein at amino acid 456 of 2285 (UniProt.org). Q456* confers a loss of function to the Arid1a protein as demonstrated by loss of Arid1a protein expression, disruption of the G2-M cell cycle checkpoint, decreased gamma-H2AX and 53BP1 foci, and decreased efficiency of homologous recombination and single-strand annealing repair of DNA in cultured cells (PMID: 26069190). |
