Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_024675.4(PALB2):c.1847A>T(p.Asp616Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,614,092 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D616G) has been classified as Uncertain significance.

Familial cancer of breast Uncertain:1
In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with PALB2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 616 of the PALB2 protein (p.Asp616Val). -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.D616V variant (also known as c.1847A>T), located in coding exon 5 of the PALB2 gene, results from an A to T substitution at nucleotide position 1847. The aspartic acid at codon 616 is replaced by valine, an amino acid with highly dissimilar properties. This amino acid position is highly 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. -
