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]

Hereditary spastic paraplegia 11 Pathogenic:2
Likely pathogenic, criteria provided, single submitterclinical testingGenome-Nilou Lab-- -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 11, 2023This sequence change creates a premature translational stop signal (p.Glu953*) in the SPG11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SPG11 are known to be pathogenic (PMID: 19105190, 20110243, 22154821, 26556829). 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: 534853). For these reasons, this variant has been classified as Pathogenic. -

Hereditary spastic paraplegia Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpAug 11, 2022Variant summary: SPG11 c.2857G>T (p.Glu953X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position are associated with Spastic paraplegia in HGMD. The variant was absent in 251164 control chromosomes (gnomAD). To our knowledge, no occurrence of c.2857G>T in individuals affected with Hereditary Spastic Paraplegia, Type 11 and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. -
not provided Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAthena DiagnosticsSep 19, 2024This variant is expected to result in the loss of a functional protein. The frequency of this variant in the general population is consistent with pathogenicity. (http://gnomad.broadinstitute.org) This variant has been identified in at least one individual tested at Athena Diagnostics with clinical features associated with this gene. -
