Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2
The NM_001166108.2(PALLD):c.2815G>C(p.Val939Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,832 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. V939I) has been classified as Uncertain significance.

Submissions by phenotype
not specified Uncertain:1
The p.V922L variant (also known as c.2764G>C), located in coding exon 15 of the PALLD gene, results from a G to C substitution at nucleotide position 2764. The valine at codon 922 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Pancreatic adenocarcinoma Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 435 of the PALLD protein (p.Val435Leu). This variant is present in population databases (rs778471055, gnomAD 0.04%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with PALLD-related conditions. ClinVar contains an entry for this variant (Variation ID: 410615). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.
