Description

The c.9117G>A pathogenic mutation (also known as p.P3039P), located in coding exon 22 of the BRCA2 gene, results from a G to A substitution at nucleotide position 9117. This nucleotide substitution does not change the at codon 3039. However, this change occurs in the last base pair of coding exon 22 and has been shown to cause aberrant RNA transcripts due to exon skipping that results in a frameshift at codon 2985 and premature protein truncation (V2985Gfs*3) (Ambry internal data; Houdayer C et al. Hum. Mutat. 2012 Aug;33:1228-38; Acedo A et al. Hum. Mutat. 2015 Feb;36:210-21). This alteration has been reported in multiple families with hereditary breast and/or ovarian cancer (Hamann U et al. J. Med. Genet. 2002 Mar;39:E12; Spurdle AB et al. J. Clin. Oncol. 2008 Apr;26:1657-63; Fong PC et al. J. Clin. Oncol. 2010 May;28:2512-9; Novakovi S et al. Int. J. Oncol. 2012 Nov;41:1619-27; Takahashi M et al. Breast Cancer. 2017 Mar;24(2):336-340; Heramb C et al. Hered Cancer Clin Pract 2018 Jan;16:3; Arai M et al. J. Hum. Genet. 2018 Apr;63(4):447-457). This alteration has also been reported in a male with aggressive prostate cancer (Willems-Jones A et al. BJU Int. 2012 Dec;110:E1181-6) and in biological males with breast cancer (de Juan I et al. Fam. Cancer. 2015 Dec;14:505-13; Corman V et al. Endocr. Relat. Cancer. 2016 May;23:391-7). Of note, this mutation is also designated as 9345G>A in published literature. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.

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.
