Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_025137.4(SPG11):c.6043G>A(p.Asp2015Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000905 in 1,614,080 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. D2015D) has been classified as Likely benign.

Hereditary spastic paraplegia 11 Uncertain:2
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 2015 of the SPG11 protein (p.Asp2015Asn). This variant is present in population databases (rs771242219, gnomAD 0.007%). This missense change has been observed in individual(s) with amyotrophic lateral sclerosis (PMID: 28160950). ClinVar contains an entry for this variant (Variation ID: 466550). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -

not specified Uncertain:1
Variant summary: SPG11 c.6043G>A (p.Asp2015Asn) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.6e-05 in 251298 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.6043G>A has been reported in the literature in a heterozygous individual affected with Amyotrophic lateral sclerosis (Nishiyama_2017). These report(s) do not provide unequivocal conclusions about association of the variant with Hereditary Spastic Paraplegia, Type 11. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 28160950). ClinVar contains an entry for this variant (Variation ID: 466550). Based on the evidence outlined above, the variant was classified as uncertain significance. -
Inborn genetic diseases Uncertain:1
The p.D2015N variant (also known as c.6043G>A), located in coding exon 32 of the SPG11 gene, results from a G to A substitution at nucleotide position 6043. The aspartic acid at codon 2015 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is well conserved in available 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. -
