- The saturation genome editing (SGE) assay for BRCA1 NM_007294.3:c.5467+5G>C, a SPLICE REGION variant, produced a function score of -1.47, corresponding to a functional classification of LOSS_OF_FUNCTION. SGE function score ranges for classification are as follows: ‘functional’, score > -0.748; ‘intermediate’, -0.748 > score > -1.328; ‘non-functional’, score < -1.328. The median synonymous SNV scored 0.0 and the median nonsense SNV scored -2.12. [submitted by Brotman Baty Institute, University of Washington]

The c.5467+5G>C intronic variant results from a G to C substitution 5 nucleotides after coding exon 21 in the BRCA1 gene. This nucleotide position is well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration may weaken the native splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing (Whiley PJ et al. Hum Mutat, 2011 Jun;32:678-87; Whiley PJ et al. Clin Chem. 2014 Feb;60(2):341-52). One functional study found that this nucleotide substitution is non-functional in a high throughput genome editing haploid cell survival assay (Findlay GM et al. Nature, 2018 Oct;562:217-222). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the majority of available evidence to date, this variant is likely to be pathogenic. (less)

HelpRecord last updated Oct 08, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
