Description

The c.9117G>A (p.Pro3039Pro) variant in the BRCA2 gene has been detected in multiple patients and families with breast and/or ovarian cancer [PMID 10638982 reported as 3398delAAAAG, 27000661] and a cohort of patients with prostate cancer [PMID 23035815, reported as c.9117 G>A (p.Val2985fs)]. The nucleotide position 9117 is the last nucleotide of exon 23. Several in vitro assays showed that the change leads aberrant splicing and the skipping of exon 23 [PMID 22505045, 23451180]. This variant is thus predicted to result in a loss of function of the protein. This variant has not been reported in the ExAC database. This variant thus classified as pathogenic.

Description

This variant changes a conserved and the last nucleotide in exon 23, and it is predicted to disrupt the intron 23 splice donor site. RNA studies have shown that this variant impacts splicing resulting in exon 23 skipping and introducing premature stop (PMID: 22505045, 23451180, 25382762, 27060066, 31843900, 32393398). This variant is expected to result in an absent or non-functional protein product. This variant has been reported in at least 10 individuals affected with breast or ovarian cancer (PMID: 18821011, 22798144, 24156927, 24249303, 25480878, 25556971, 25948282, 26026974, 27000661, 28477318, 28724667, 30287823). This variant has been identified in 1/248378 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BRCA2 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.
