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 submitter	clinical testing	Genome-Nilou Lab	-	- -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 22, 2023	For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 572602). This premature translational stop signal has been observed in individual(s) with hereditary spastic paraplegia (PMID: 23733235). This variant is present in population databases (rs141263564, gnomAD 0.003%). This sequence change creates a premature translational stop signal (p.Lys2200*) 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). -

The SPG11 c.6598A>T variant is predicted to result in premature protein termination (p.Lys2200*). This variant was reported in the compound heterozygous state with another loss-of-function variant in two patients with autosomal recessive spastic paraplegia (Yoon et al. 2013. PubMed ID: 23733235; Carrasco Salas et al. 2022. PubMed ID: 33059505). This variant is reported in 0.0039% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Nonsense variants in SPG11 are expected to be pathogenic. This variant is interpreted as pathogenic. -
