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:3
Pathogenic, criteria provided, single submitterclinical testingGenome-Nilou Lab-- -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 14, 2023This sequence change creates a premature translational stop signal (p.Glu1819Alafs*10) 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 present in population databases (rs749819954, gnomAD 0.007%). This premature translational stop signal has been observed in individuals with autosomal recessive hereditary spastic paraplegia (PMID: 18337587; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 41368). For these reasons, this variant has been classified as Pathogenic. -

Inborn genetic diseases Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2021The c.5456_5457delAG pathogenic mutation, located in coding exon 30 of the SPG11 gene, results from a deletion of two nucleotides at nucleotide positions 5456 to 5457, causing a translational frameshift with a predicted alternate stop codon (p.E1819Afs*10). This mutation was detected in a compound heterozygous state with other truncating alterations in SPG11 in two siblings and one additional unrelated individual, all of whom had phenotypes consistent with hereditary spastic paraplegia (Paisan-Ruiz C et al. Neurology, 2008 Apr;70:1384-9; Kara E et al. Brain, 2016 07;139:1904-18). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
