Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_025137.4(SPG11):c.2924T>C(p.Leu975Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,762 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. L975L) has been classified as Likely benign.

Hereditary spastic paraplegia 11 Uncertain:1
This sequence change replaces leucine with proline at codon 975 of the SPG11 protein (p.Leu975Pro). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs758207568, ExAC 0.01%) but has not been reported in the literature in individuals with a SPG11-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. -
