Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_025137.4(SPG11):c.6391C>T(p.His2131Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.00000372 in 1,613,962 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 (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H2131N) has been classified as Uncertain significance.

Hereditary spastic paraplegia 11 Uncertain:1
This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 2131 of the SPG11 protein (p.His2131Tyr). This variant is present in population databases (rs775209503, gnomAD 0.01%). 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: 2199808). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt SPG11 protein function with a positive predictive value of 80%. 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. -
