| Gene Variant Descriptions | BARD1 P187A does not lie within any known functional domains of the Bard1 protein (UniProt.org). P187A results in altered subcellular localization, decreased Brca1, Palb2, and Rad51c interaction, impaired homology-directed DNA repair activity, decreased DNA repair post-irradiation, decreased H2A ubiquitination, and increased sensitivity to olaparib and cisplatin treatment in cultured cells (PMID: 39387837). |
