Submissions by phenotype
not provided Uncertain:2
- -
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Hereditary spastic paraplegia 11 Uncertain:2
This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 1357 of the SPG11 protein (p.Leu1357Pro). This variant is present in population databases (rs367550468, gnomAD 0.005%). 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: 406534). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SPG11 protein function with a negative predictive value of 80%. 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. -

Inborn genetic diseases Uncertain:1
The p.L1357P variant (also known as c.4070T>C), located in coding exon 24 of the SPG11 gene, results from a T to C substitution at nucleotide position 4070. The leucine at codon 1357 is replaced by proline, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. 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. -
