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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.4085T>C (p.L1362P) alteration is located in exon 24 (coding exon 24) of the SPG11 gene. This alteration results from a T to C substitution at nucleotide position 4085, causing the leucine (L) at amino acid position 1362 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Hereditary spastic paraplegia 11 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 28, 2021This sequence change replaces leucine with proline at codon 1362 of the SPG11 protein (p.Leu1362Pro). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs757078269, ExAC 0.004%). 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: 406513). 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. -
