RCV001043412 | SCV001207158 | uncertain significance | Hereditary spastic paraplegia 11 | 2022-09-06 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with isoleucine, which is neutral and non-polar, at codon 1025 of the SPG11 protein (p.Lys1025Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SPG11-related conditions. ClinVar contains an entry for this variant (Variation ID: 841229). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 | RCV002319652 | SCV002608672 | uncertain significance | Inborn genetic diseases | 2020-03-19 | criteria provided, single submitter | clinical testing | The p.K1025I variant (also known as c.3074A>T), located in coding exon 17 of the SPG11 gene, results from an A to T substitution at nucleotide position 3074. The lysine at codon 1025 is replaced by isoleucine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. 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. |

RCV001043412 | SCV002768390 | uncertain significance | Hereditary spastic paraplegia 11 | 2020-05-25 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v0.6.1, this variant is classified as 3B-VUS. Following criteria are met: 0102 - Loss of function is a known mechanism of disease for this gene. 0106 - This gene is known to be associated with autosomal recessive disease. 0200 - Variant is predicted to result in a missense amino acid change from lysine to isoleucine (exon 17). 0301 - Variant is absent from gnomAD. 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. 0604 - Variant is not located in an established domain, motif or hotspot. 0705 - No comparable variants in relevant codon/region have previous evidence for pathogenicity. 0807 - Variant has not previously been reported in a clinical context. 0905 - No published segregation evidence has been identified for this variant. 1007 - No published functional evidence has been identified for this variant. |
