| Protein Effect | loss of function |
| Gene Variant Descriptions | RAD51C D141H does not lie within any known functional domains of the Rad51c protein (UniProt.org). D141H confers a loss of function to Rad51c as demonstrated by reduced homology-directed DNA repair activity, abnormal replication fork progression leading to accumulation of ssDNA breaks in culture, defective interaction with Rad51d in a yeast assay (PMID: 42625895), and decreased survival in a high-throughput cell culture assay (PMID: 39299233). |
