GeneDx	RCV000212733	SCV000149712	pathogenic	not provided	2021-11-11	criteria provided, single submitter	clinical testing	Frameshift variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Case control studies suggest this variant is associated with prostate cancer; earlier studies also describe associated risk for breast cancer and lymphoma, though additional studies have not been supportive (Zhang 2012, Cybulski 2013, Gao 2013, Rogoa-Janiszewska 2020, Wokoorczyk 2020, Hu 2021); Also known as 657del5; This variant is associated with the following publications: (PMID: 9590180, 19908051, 23317186, 32255556, 18073374, 24619942, 26929905, 28649662, 29785153, 30426508, 30322717, 30612635, 22131123, 22293976, 25485873, 23765759, 16770759, 23149842, 22941933, 19635536, 14973119, 19452044, 16033915, 27150568, 27038244, 19393249, 27276934, 26083025, 26822949, 25980754, 27616075, 28008555, 26681312, 28374160, 28873162, 28376765, 25186627, 15185344, 11093281, 18606567, 11279524, 16544999, 11953735, 18940477, 12833396, 12505263, 12123493, 10852373, 10398434, 9620777, 29368341, 29915322, 29555771, 29753700, 28152038, 26265251, 31173646, 30590007, 31187634, 31159747, 29419426, 31980526, 33178177, 31589614, 32338768, 33488600, 32441320, 32843899, 24113799, 33077847, 32427313)
Ambry Genetics	RCV000133576	SCV000183792	pathogenic	Hereditary cancer-predisposing syndrome	2021-08-13	criteria provided, single submitter	clinical testing	The c.657_661delACAAA pathogenic mutation, located in coding exon 6 of the NBN gene, results from a deletion of 5 nucleotides at positions 657 to 661, causing a translational frameshift with a predicted alternate stop codon (p.K219Nfs*16). The c.657_661delACAAA mutation (commonly referred to as 657del5 in the literature) is the most common NBN mutation in Eastern European individuals with Nijmegen Breakage Syndrome (Varon R et al. Eur. J. Hum. Genet., 2000 Nov;8:900-2). This mutation has been reported with increased frequency in individuals with medulloblastoma, prostate cancer, pancreatic cancer, melanoma, breast cancer, colon cancer, and non-Hodgkin's lymphoma (Borecka M et al. Gene, 2016 Aug;587:169-72; Ciara E et al. Acta Neuropathol., 2010 Mar;119:325-34; Cybulski C et al. Cancer Res., 2004 Feb;64:1215-9; Domagala P et al. PLoS ONE, 2015 Jun;10:e0130393; Kraus C et al. Int. J. Cancer. 2017 Jan;140:95-102; Lhota F et al. Clin. Genet., 2016 Oct;90:324-33; Steffen J et al. Int. J. Cancer, 2004 Aug;111:67-71). This variant has also been observed, in the homozyous and compound heterozygous state, in patients with Nijmegen Breakage syndrome (Matsuura S et al. Nat Genet, 1998 Jun;19:179-81; Kleier S et al. Clin Genet, 2000 May;57:384-7; Szczauba K et al. J. Appl. Genet., 2012 May;53:189-91). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. However, functional studies have indicated that this alteration may partially escape nonsense-mediated decay and produce a protein with some residual function (Maser RS et al. Nat Genet, 2001 Apr;27:417-21). Based on the supporting clinical evidence, this alteration is interpreted as a disease-causing mutation.
Invitae	RCV000007353	SCV000218835	pathogenic	Microcephaly, normal intelligence and immunodeficiency	2024-01-29	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Lys219Asnfs*16) in the NBN gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 536 amino acid(s) of the NBN protein. This variant is present in population databases (rs587776650, gnomAD 0.04%). This premature translational stop signal has been observed in individual(s) with NBN-related conditions (PMID: 14973119, 15185344, 18606567, 19908051, 24113799). It is commonly reported in individuals of Slavic ancestry (PMID: 9590180). This variant is also known as 657del5. ClinVar contains an entry for this variant (Variation ID: 6940). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects NBN function (PMID: 16033915, 22131123, 22941933). For these reasons, this variant has been classified as Pathogenic.

PreventionGenetics, part of Exact Sciences	RCV003389666	SCV000806448	pathogenic	NBN-related disorder	2023-03-03	criteria provided, single submitter	clinical testing	The NBN c.657_661del5 variant is predicted to result in a frameshift and premature protein termination (p.Lys219Asnfs*16). The c.657_661del variant (also known as c.657del5) in the NBN gene is a founder pathogenic variant in the Slavic population and causes Nijmegen breakage syndrome in the homozygous state or in combination with another pathogenic variant in NBN (Varon et al. 1998. PubMed ID: 9590180). Functionally, it has been hypothesized to be a hypomorph, which results in a truncated protein with residual activity of the full-length NBN protein (Maser et al. 2001. PubMed ID: 11279524; Dzikiewicz-Krawczyk et al. 2011. PubMed ID: 22131123). However, this variant has been reported in up to ~0.04% of individuals (primarily within Europeans) in a large population database of presumably healthy individuals (http://gnomad.broadinstitute.org/variant/8-90983441-ATTTGT-A). In ClinVar, this variant has been classified as pathogenic as well as a risk factor (https://www.ncbi.nlm.nih.gov/clinvar/variation/6940/). Frameshift variants in NBN are expected to be pathogenic. This variant is interpreted as pathogenic.
GeneKor MSA	RCV000133576	SCV000821748	pathogenic	Hereditary cancer-predisposing syndrome	2021-01-09	criteria provided, single submitter	clinical testing	This is a deletion of five base pairs from exon 6 of the NBN mRNA (c.657_661delACAAA), which results in frameshift after codon 219 and creation of a novel stop codon 16 amino acid residues later and would generally be expected to result in an absent or disrupted protein product.This is the most common variant reported in individuals affected with Nijmegen breakage syndrome (NBS), and is considered to be a founder mutation in the Slavic population (PMID: 9590180). It is also known as 657del5 in the literature. Heterozygous carriers may have increased risk for several types of cancers including breast, lymphoma, melanoma, medulloblastoma, prostate and others (PMID: 15185344, 14973119, 18606567, 19908051, 24113799). Experimental studies propose that this deletion encodes a partially functional protein that diminishes the severity of the NBS phenotype (PMID: 11279524). The mutation database Clinvar contains entries for this variant (Variation ID:6940).

Quest Diagnostics Nichols Institute San Juan Capistrano	RCV000212733	SCV000889554	pathogenic	not provided	2022-08-22	criteria provided, single submitter	clinical testing	This frameshift variant alters the translational reading frame of the NBN mRNA and causes the premature termination of NBN protein synthesis. Functional studies have shown that this variant results in two proteins, the N-terminal p26 fragment and the p70 fragment produced from an internal initiation codon at position p.221 that lacks the N-terminal portion (PMID: 11279524 (2001), 25485873 (2014)). Another study has shown that the variant caused increased chromosomal instability in homozygous cells (PMID: 22131123 (2012)). The frequency of this variant in the general population, 0.00041 (21/50678 chromosomes, http://gnomad.broadinstitute.org), is consistent with pathogenicity. The c.657_661del variant is the most common pathogenic variant found in individuals affected by Nijmegen breakage syndrome (NBS) (PMID: 9590180 (1998), 20301355 (2017)). In the published literature, previous studies showed an association to breast cancer (PMID: 12845677 (2003), 22491912 (2012), 23317186 (2012)), however, recent studies do not support this association (PMID: 34072463 (2021), 33471974 (2021), 33471991 (2021)). The variant is also reported to have an increased risk overall for cancer (PMID: 24113799 (2013), 15185344 (2004)), including pancreatic cancer (PMID: 27150568 (2016), 35309086 (2022)), prostate cancer (PMID: 14973119 (2004)), medulloblastoma (PMID: 19908051 (2010)), and relapse of B-cell precursor acute lymphoblastic leukemia (BCP-ALL) (PMID: 29419426 (2018)). Based on the available information, this variant is classified as pathogenic.
ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV000212733	SCV001160103	pathogenic	not provided	2023-11-14	criteria provided, single submitter	clinical testing	The NBN c.657_661del; p.Lys219AsnfsTer16 variant (rs587776650), also known as 657del5, is reported in the literature as the most common pathogenic variant and a founder mutation in the Slavic population in individuals affected with Nijmegen breakage syndrome (Varon 1998). Heterozygous carriers are also reported to have an increased risk for various cancers, including breast cancer, prostate cancer, colorectal cancer, lymphoma, melanoma, and medulloblastoma (Ciara 2010, Gao 2013, Steffen 2004). However, more recent large, multi-ethnic case control studies have demonstrated that heterozygous pathogenic NBN variants are not associated with an increased risk for breast cancer (Breast Cancer Association Consortium 2021, Hu 2021). Data regarding other cancer risks remains inconclusive. This variant is reported as pathogenic by multiple laboratories in ClinVar (Variation ID: 6940), and is found in the non-Finnish European population with an allele frequency of 0.040% (52/128,774 alleles) in the Genome Aggregation Database. This variant causes a frameshift by deleting 5 nucleotides, so it is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. However, functional studies show two in-frame start codons created by the frameshift that can generate truncated NBN proteins with partial functionality (Lins 2009, Maser 2001). Based on available information, the p.Lys219AsnfsTer16 variant is considered to be pathogenic. References: Breast Cancer Association Consortium, Dorling L, Carvalho S, et al.

Additionally, in the heterozygous state, this variant has been found to increase risk to certain NBS-related cancers (Gao 2013, Zhang 2012). It has also been identified in 52/128774 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). However, this frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (Variation ID: 6940). This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 219 and leads to a premature termination codon 16 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Loss of function of the NBN gene is an established disease mechanism in autosomal recessive NBS. In vitro functional studies support an impact on protein function and show that this variant leads to the production of an abnormal protein product (Maser 2001, Dzikiewicz-Krawczyk 2012). In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive NBS. ACMG/AMP criteria applied: PVS1, PM3_VeryStrong, PS3_Supporting.

This change is predicted to cause protein truncation or absence of the protein due to nonsense mediated decay. This variant has a maximum subpopulation frequency of 0.040% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). This is the most common pathogenic variant reported in individuals affected with Nijmegen breakage syndrome (PMID: 9590180, 20301355). In addition, this variant has been identified as heterozygous in individuals with many cancer types including breast, lymphoma, prostate, melanoma, medulloblastoma, and others (PMID: 15185344, 14973119, 18606567, 19908051, 24113799). Case-control studies have demonstrated evidence of association with breast cancer (OR = 2.63), prostate cancer (OR = 5.87), and lymphoma (OR = 2.93) (PMID: 23317186, 24113799). This variant is present 5x in the FLOSSIES database which contains genetic variants from women older than 70 years of age who have never had cancer (https://whi.color.com/). In summary, this variant meets criteria to be classified as pathogenic.

Large meta-analyses have reported significant odds ratios in carriers of the variant for multiple cancers, particularly breast cancer (OR = 2.63 [95% CI=1.76-3.93]), prostate cancer (OR = 5.87 [95% CI=2.51-13.75]), and lymphoma (OR = 2.93 [95% CI=1.62-5.29]) (Gao 2013, Zhang 2012). Additionally, in the bi-allelic state, this variant is the most common variant associated with autosomal recessive Nijmegen Breakage Syndrome (NBS). It has also been identified in 52/128774 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID: 6940). This variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 219 and leads to a premature termination codon 16 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Loss of function of the NBN gene is an established disease mechanism in autosomal recessive NBS. In vitro functional studies support an impact on protein function and show that this variant leads to the production of an abnormal protein product (Maser 2001, Dzikiewicz-Krawczyk 2012). In summary, this variant meets criteria to be classified as an established risk allele for breast, prostate, and lymphoid cancers.

This variant is a Slavic founder mutation with carrier frequency among newborns in the range of 1/154 in the Czech Republic to 1/190 in Poland (Steffen 2004). The variant was also identified in dbSNP (ID: rs587776650 as "With Pathogenic allele"), ClinVar (classified as pathogenic by Invitae, GeneDx, Ambry Genetics and twelve other submitters), and LOVD 3.0 (4x). The variant was identified in control databases in 55 of 276598 chromosomes at a frequency of 0.0002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European in 50 of 126360 chromosomes (freq: 0.0004), Other in 1 of 6436 chromosomes (freq: 0.0002), Finnish in 2 of 25738 chromosomes (freq: 0.00008), and Latino in 2 of 34324 chromosomes (freq: 0.00006); it was not observed in the African, Ashkenazi Jewish, East Asian, or South Asian populations. Functional studies have reported that the variant leads to two truncated fragments, p26 and p70 nibrin, and the translation of a short N-terminal protein with FHA/BRCT domains, therefore maintaining some function of the full-length NBS1 protein (Dzikiewicz-Krawczyk 2008, Cilli 2014). The variant has been associated with an increased risk of breast cancer and medulloblastoma, and a significant increase in overall cancer risks (Zhang 2013, Ciara 2010, Gao 2013, Borecka 2016). The c.657_661del variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 219 and leads to a premature stop codon at position 234. This alteration is then predicted to result in a truncated or absent protein and loss of function. Loss of function variants of the NBN gene are an established mechanism of disease in NBN-associated cancer and is the type of variant expected to cause the disorder. In summary, based on the above information, this variant meets our laboratory’s criteria to be classified as pathogenic.
