RCV001993209 | SCV002236448 | pathogenic | Microcephaly, normal intelligence and immunodeficiency | 2022-05-28 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1451317). This variant has not been reported in the literature in individuals affected with NBN-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Pro283Leufs*11) in the NBN gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NBN are known to be pathogenic (PMID: 9590180, 16415040). |

RCV001993209 | SCV002602540 | likely pathogenic | Microcephaly, normal intelligence and immunodeficiency | 2022-01-15 | criteria provided, single submitter | clinical testing | NM_002485.4(NBN):c.848delC(P283Lfs*11) is expected to be pathogenic in the context of Nijmegen breakage syndrome. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in NBN, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening. |
Ambry Genetics | RCV003348687 | SCV004051378 | pathogenic | Hereditary cancer-predisposing syndrome | 2023-06-22 | criteria provided, single submitter | clinical testing | The c.848delC pathogenic mutation, located in coding exon 7 of the NBN gene, results from a deletion of one nucleotide at nucleotide position 848, causing a translational frameshift with a predicted alternate stop codon (p.P283Lfs*11). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |
