Norman-Roberts syndrome;C4225327:Familial temporal lobe epilepsy 7 Uncertain:1
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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RELN-related disease. This variant is present in population databases (rs143688278, ExAC 0.001%). This sequence change replaces aspartic acid with valine at codon 2352 of the RELN protein (p.Asp2352Val). The aspartic acid residue is moderately conserved and there is a large physicochemical difference between aspartic acid and valine. -
RELN-related disorder Uncertain:1
The RELN c.7055A>T variant is predicted to result in the amino acid substitution p.Asp2352Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0023% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
