Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2
The NM_025137.4(SPG11):āc.1184A>Cā(p.Gln395Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,884 control chromosomes in the GnomAD database, with no homozygous occurrence. 14/21 in silico tools predict a benign 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. Q395R) has been classified as Uncertain significance.

Hereditary spastic paraplegia 11 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 05, 2021 | This sequence change replaces glutamine with proline at codon 395 of the SPG11 protein (p.Gln395Pro). The glutamine residue is weakly conserved and there is a moderate physicochemical difference between glutamine and proline. 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The proline amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with SPG11-related conditions. This variant is not present in population databases (ExAC no frequency). - |
