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:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Mar 17, 2022	This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1867 of the SPG11 protein (p.Glu1867Lys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 534857). 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. 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. -

Ambry Genetics

Jun 14, 2023

The c.5599G>A (p.E1867K) alteration is located in exon 30 (coding exon 30) of the SPG11 gene. This alteration results from a G to A substitution at nucleotide position 5599, causing the glutamic acid (E) at amino acid position 1867 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
