NM_001166108.2:c.3146G>A
Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2
The NM_001166108.2(PALLD):c.3146G>A(p.Arg1049His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000217 in 1,613,752 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. R1049C) has been classified as Likely benign.

not specified Uncertain:1
The p.R545H variant (also known as c.1634G>A), located in coding exon 9 of the PALLD gene, results from a G to A substitution at nucleotide position 1634. The arginine at codon 545 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
Pancreatic adenocarcinoma Uncertain:1
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 545 of the PALLD protein (p.Arg545His). This variant is present in population databases (rs755223646, gnomAD 0.003%). 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: 542933). 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 disruptive. 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. -
