RCV001325312 | SCV001516300 | uncertain significance | Hereditary pancreatitis | 2022-07-23 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 162 of the PRSS1 protein (p.Asp162Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PRSS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1025047). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
| Ambry Genetics | RCV001325312 | SCV002635586 | uncertain significance | Hereditary pancreatitis | 2024-01-31 | criteria provided, single submitter | clinical testing | The p.D162E variant (also known as c.486T>A), located in coding exon 4 of the PRSS1 gene, results from a T to A substitution at nucleotide position 486. The aspartic acid at codon 162 is replaced by glutamic acid, an amino acid with highly similar properties. This amino acid position is conserved. 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. |
