Description

The p.D674A variant (also known as c.2021A>C), located in coding exon 5 of the PALB2 gene, results from an A to C substitution at nucleotide position 2021. The aspartic acid at codon 674 is replaced by alanine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
