| Gene | RAD51D |
| Variant | V200* |
| Impact List | nonsense |
| Protein Effect | loss of function |
| Gene Variant Descriptions | RAD51D V200* results in a premature truncation of the Rad51d protein at amino acid 200 of 328 (UniProt.org). V200* results in decreased Rad51d protein stability, impaired DNA homologous recombination activity and DNA damage response, and increased sensitivity to PARP inhibitors in culture (PMID: 33151324). |
