Genes affected

BRAP (HGNC:1099): (BRCA1 associated protein) The protein encoded by this gene was identified by its ability to bind to the nuclear localization signal of BRCA1 and other proteins. It is a cytoplasmic protein which may regulate nuclear targeting by retaining proteins with a nuclear localization signal in the cytoplasm. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1259G>A (p.R420Q) alteration is located in exon 10 (coding exon 10) of the BRAP gene. This alteration results from a G to A substitution at nucleotide position 1259, causing the arginine (R) at amino acid position 420 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
