Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_025137.4(SPG11):ā€‹c.5645T>Gā€‹(p.Ile1882Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000684 in 1,461,888 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I1882T) has been classified as Uncertain significance.

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 testingInvitaeAug 12, 2022This sequence change replaces isoleucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 1882 of the SPG11 protein (p.Ile1882Ser). This variant is present in population databases (rs760815236, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with SPG11-related conditions. 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 disruptive. 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. -
