Genes affected

SPG11 (HGNC:11226): (SPG11 vesicle trafficking associated, spatacsin) The protein encoded by this gene is a potential transmembrane protein that is phosphorylated upon DNA damage. Defects in this gene are a cause of spastic paraplegia type 11 (SPG11). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

The c.2087T>G (p.I696S) alteration is located in exon 11 (coding exon 11) of the SPG11 gene. This alteration results from a T to G substitution at nucleotide position 2087, causing the isoleucine (I) at amino acid position 696 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces isoleucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 696 of the SPG11 protein (p.Ile696Ser). This variant is present in population databases (rs150746549, gnomAD 0.02%). 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: 466512). 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: "Benign"; 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. -
