This nucleotide position is highly conserved in available vertebrate species. This alteration is at a branch point which is a pre-mRNA feature that is important for correct splicing (Leman R et al. BMC Genomics, 2020 Jan;21:86; Canson D et al. Hum. Mutat., 2020 Jul). This alteration has been identified in several patients with breast and/or ovarian cancer (Bisgin A et al. Breast J., 2019 09;25:1029-1033; Tabarestani S et al. Int. J. Cancer Manag., 2017 10(12):e60392; CanVig Data-ClinVar). This variant has also been identified in the homozygous state in an adult with normal chromosome breakage studies (Personal communication). In silico splice site analysis for this alteration is inconclusive. RNA studies have demonstrated that this alteration results in a substantial but incomplete splice defect; however the clinical impact of this abnormal splicing is unknown at this time (Ambry internal data; CanVIG Data-ClinVar, Personal communication; Wai HA et al. Genet. Med., 2020 Jun;22:1005-1014; Leman R et al. BMC Genomics, 2020 Jan;21:86). This nucleotide substitution is functional in a high throughput genome editing haploid cell survival assay that can measure both protein and RNA effects (Findlay GM et al. Nature, 2018 10;562:217-222). Since supporting evidence is conflicting at this time, the clinical significance of this alteration remains unclear. (less)

It does not directly change the encoded amino acid sequence of the BRCA1 protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with breast cancer (PMID: 16544996, 31228304, 34981296). ClinVar contains an entry for this variant (Variation ID: 125786). Studies have shown that this variant results in skipping of exon 18 and introduces a premature termination codon (PMID: 32123317; Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. (less)

This nucleotide position is highly conserved in available vertebrate species. This alteration is at a branch point which is a pre-mRNA feature that is important for correct splicing (Leman R et al. BMC Genomics, 2020 Jan;21:86; Canson D et al. Hum. Mutat., 2020 Jul). This alteration has been identified in several patients with breast and/or ovarian cancer (Bisgin A et al. Breast J., 2019 09;25:1029-1033; Tabarestani S et al. Int. J. Cancer Manag., 2017 10(12):e60392; CanVig Data-ClinVar). This variant has also been identified in the homozygous state in an adult with normal chromosome breakage studies (Personal communication). In silico splice site analysis for this alteration is inconclusive. RNA studies have demonstrated that this alteration results in a substantial but incomplete splice defect; however the clinical impact of this abnormal splicing is unknown at this time (Ambry internal data; CanVIG Data-ClinVar, Personal communication; Wai HA et al. Genet. Med., 2020 Jun;22:1005-1014; Leman R et al. BMC Genomics, 2020 Jan;21:86). This nucleotide substitution is functional in a high throughput genome editing haploid cell survival assay that can measure both protein and RNA effects (Findlay GM et al. Nature, 2018 10;562:217-222). Since supporting evidence is conflicting at this time, the clinical significance of this alteration remains unclear.

Comment:

Data included in classification: Case control comparison of UK familial cases against ethnically matched population data (7/25,773 in familial UK cases against 0/23,509 NFE controls from GnomAD genome sequencing and UK 100,000 genome project pexact= 0.016) (PS4_strong). 1/8 segregation in one large UK family (PP1_sup). UK Family 1: Homozygous Iranian case (from consanguineous family) with normal phenotype in adulthood (age 34), no cancer and normal chromosome breakage in lymphocytes. Additional studies inc. RNA and skin biopsy were sought from this patient could not be attained. (BS2_strong). Absent from the remainder of the GnomAD population (PM2_sup). Additional data (not included in classification): In silico analysis supports aberration of splicing compared to WT due to experimentally-proven intronic branch site. Functional evidence conflicting: Mini-gene assay: suggestive of incomplete skipping of exon 19. Published RNA analyses: estimated that transcripts lacking exon 19 (41bp) account for 30-40% of all BRCA1 transcripts in blood, inferring that 10-20% of transcripts expressed from the variant allele are of full length. See also: Steffensen et al Eur J Hum Genet 2014, Rosenthal ET et al, Clin Genet 2015, Mercer, Genome Res 2015. Patient-derived RNA assay from UK diagnostic labs demonstrated the variant to cause out of frame deletion of exon 19. This results in a PTC in exon 20. Estimation that transcripts lacking exon 19 account for 30-40% of all BRCA1 transcripts in blood. Haploid yeast saturation genome editing assay shown to be functional (Findlay et al, 2018).

Comment:

This sequence change falls in intron 17 of the BRCA1 gene. It does not directly change the encoded amino acid sequence of the BRCA1 protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individual(s) with breast cancer (PMID: 16544996, 31228304, 34981296). ClinVar contains an entry for this variant (Variation ID: 125786). Studies have shown that this variant results in skipping of exon 18 and introduces a premature termination codon (PMID: 32123317; Invitae). The resulting mRNA is expected to undergo nonsense-mediated decay. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
