Description

This pathogenic variant is denoted BRCA1 c.5075-1 G>A or IVS16-1 G>A and consists of a G>A nucleotide substitution at the -1 position of intron 16 of the BRCA1 gene. The variant destroys a canonical splice acceptor site and is predicted to cause abnormal gene splicing, leading to either an abnormal message that is subject to nonsense-mediated mRNA decay or to an abnormal protein product. This variant, also known as BRCA1 c.5194-1G>A using alternate nomenclature, has been reported to be pathogenic in association with hereditary breast cancer (Jara 2006). We therefore consider this variant to be pathogenic.
