ClinVar
Submissions by phenotype
not specified Uncertain:1
The p.R876Q variant (also known as c.2627G>A), located in coding exon 14 of the PALLD gene, results from a G to A substitution at nucleotide position 2627. The arginine at codon 876 is replaced by glutamine, 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 arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 389 of the PALLD protein (p.Arg389Gln). This variant is present in population databases (rs747702421, gnomAD 0.01%). 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: 572905). 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. -
