RCV001370315 | SCV001566786 | uncertain significance | Multiple congenital anomalies-hypotonia-seizures syndrome 1 | 2022-06-13 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 510 of the PIGN protein (p.Val510Ile). This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with PIGN-related conditions. ClinVar contains an entry for this variant (Variation ID: 1060834). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The isoleucine 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 | RCV004952840 | SCV005469368 | uncertain significance | Inborn genetic diseases | 2024-10-06 | criteria provided, single submitter | clinical testing | The c.1528G>A (p.V510I) alteration is located in exon 17 (coding exon 14) of the PIGN gene. This alteration results from a G to A substitution at nucleotide position 1528, causing the valine (V) at amino acid position 510 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
