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:3

Likely pathogenic, no assertion criteria provided	clinical testing	Genomics England Pilot Project, Genomics England	-	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 03, 2023	This sequence change creates a premature translational stop signal (p.Trp362*) 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 (rs140385286, gnomAD 0.009%). This premature translational stop signal has been observed in individual(s) with hereditary spastic paraplegia type 11 (PMID: 23443022). ClinVar contains an entry for this variant (Variation ID: 488833). For these reasons, this variant has been classified as Pathogenic. -
