Pathogenic, criteria provided, single submitter | research | UAEU Genomics Laboratory, United Arab Emirates University | Apr 08, 2023 | The in-frame deletion NM_006345.4(SLC30A9):c.1049_1051delCAG (p.Ala350del) has been reported previously in 6 individuals from a Bedouin kindred affected with Birk-Landau-Perez syndrome (Perez et al., 2017). This variant is not present in gnomAD database (Karczewski et al., 2020) and Middle Eastern specific databases (Koshy et al., 2017). The removed amino acid is highly conserved and is located at the predicted cation-efflux domain of the mature SLC30A9 protein. In vitro functional studies in human neuroblastoma cells showed a significant decrease in cytosolic free Zn2+ levels in cells expressing the mutant compared to the wild type. (Perez et al., 2017).Further, in CRISPR-Cas9 knockout (SLC30A9 -/-) cell lines, functional complementation of the p.Ala350Del variant failed to restore the functional defect caused by genetic ablation of SLC30A9, indicating that the p.Ala350Del variant is a loss-of-function allele (Deng et al., 2021). Aggregating all the available evidence (PM2, PM1, PS3, PP1_strong), this variant has been classified as Pathogenic. - |
