Genes affected

APPBP2 (HGNC:622): (amyloid beta precursor protein binding protein 2) The protein encoded by this gene interacts with microtubules and is functionally associated with beta-amyloid precursor protein transport and/or processing. The beta-amyloid precursor protein is a cell surface protein with signal-transducing properties, and it is thought to play a role in the pathogenesis of Alzheimer's disease. The encoded protein may be involved in regulating cell death. This gene has been found to be highly expressed in breast cancer. Alternative splicing results in multiple transcript variants.

The c.1711G>C (p.V571L) alteration is located in exon 13 (coding exon 13) of the APPBP2 gene. This alteration results from a G to C substitution at nucleotide position 1711, causing the valine (V) at amino acid position 571 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
