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	Invitae	Oct 25, 2022	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 966 of the SPG11 protein (p.Arg966His). This variant is present in population databases (rs200281262, gnomAD 0.03%). 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: 534861). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SPG11 protein function. 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. -

The p.R966H variant (also known as c.2897G>A), located in coding exon 16 of the SPG11 gene, results from a G to A substitution at nucleotide position 2897. The arginine at codon 966 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and histidine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
