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]

Pathogenic, criteria provided, single submitterclinical testingInvitaeJan 26, 2024This sequence change creates a premature translational stop signal (p.Glu2247Leufs*14) 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 (rs312262782, gnomAD 0.009%). This premature translational stop signal has been observed in individuals with hereditary spastic paraplegia (PMID: 18079167, 20301389, 20571989, 23443022, 26556829). ClinVar contains an entry for this variant (Variation ID: 41348). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2022The c.6739_6742delGAGT pathogenic mutation, located in coding exon 36 of the SPG11 gene, results from a deletion of 4 nucleotides at nucleotide positions 6739 to 6742, causing a translational frameshift with a predicted alternate stop codon (p.E2247Lfs*14). This alteration has been detected as compound heterozygous or homozygous in multiple unrelated individuals with SPG11-related neurologic disorders (Stevanin G et al. Brain, 2008 Mar;131:772-84; de Bot ST et al. Eur J Hum Genet, 2013 Nov;21:1312-5; Denora PS et al. Brain, 2016 06;139:1723-34; Montecchiani C et al. Brain, 2016 Jan;139:73-85). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. -
