Description

Nonsense 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; Published functional studies demonstrate occasional alternate splicing resulting in both the pathogenic deletion of exon 7 or the in-frame naturally occurring deletion of exons 4-7 which may result in a functional protein (Biswas 2011, Di Giacomo 2013, Mesman 2020); Observed in multiple individuals with Hereditary Breast and Ovarian Cancer (Couch 1996, Shih 2002, Francies 2015, Yang 2017, Chan 2018); Not observed at significant frequency in large population cohorts (Lek 2016); Truncating variants in this gene are considered pathogenic by a well-established clinical consortium and/or database; Also known as 809G>A; This variant is associated with the following publications: (PMID: 22962691, 26920070, 23983145, 8673091, 21719596, 25652403, 11844822, 28664506, 28301456, 26577449, 30093976, 29843852, 29446198, 32398771, 32393813)

Description

DNA sequence analysis of the BRCA2 gene demonstrated a sequence change, c.581G>A, which results in the creation of a premature stop codon at amino acid position 194, p.Trp194*. This pathogenic sequence change is predicted to result in an abnormal transcript, which may be degraded, or may lead to the production of a truncated BRCA2 protein with potentially abnormal function. In vitro assays have provided evidence that the p.Trp194* sequence change leads to skipping of exon 7, altered protein nuclear localization and reduced p53 phosphorylation (Loke et al., 2015. Hum Mol Genet 24: 3030-7; Di Giacomo et al., 2013. Hum Mutat 34: 1547-57). This pathogenic sequence change has previously been described in a patient with BRCA2-related breast cancer (PMID: 8673091).
