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 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 28, 2022This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 594 of the SPG11 protein (p.Ile594Val). This variant is present in population databases (rs762177930, gnomAD 0.002%). 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: 582658). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
