Purpose: Mutations in RAD51D are associated with a predisposition to primary ovarian, fallopian tube, and peritoneal carcinoma. Our study aims to characterize a RAD51D missense variant in a hereditary ovarian cancer family. Methods: The effects of the RAD51D c.82G>A (p.Val28Met) variant on mRNA splicing were evaluated and characterized using RT-PCR, cloning and DNA sequencing. Results: This variant completely disrupts normal splicing and results in the loss of 3′end of 5′UTR and the entire exon 1 (c.-86_c.82), which presumably leads to loss of the RAD51D protein. The RAD51D c.82G>A (p.Val28Met) variant is clinically significant and classified as likely pathogenic. Conclusions: Our results indicate that the RAD51D c.82G>A (p.Val28Met) variant contributes to cancer predisposition through disruption of normal mRNA splicing. The identification of this variant in an individual affected with high-grade serous fallopian tube cancer suggests that the RAD51D variant may contribute to predisposition to the ovarian cancer in this family. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature. |
