Inborn genetic diseases Uncertain:1
The c.6401A>G (p.E2134G) alteration is located in exon 42 (coding exon 42) of the RELN gene. This alteration results from a A to G substitution at nucleotide position 6401, causing the glutamic acid (E) at amino acid position 2134 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
Norman-Roberts syndrome;C4225327:Familial temporal lobe epilepsy 7 Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 2134 of the RELN protein (p.Glu2134Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RELN-related conditions. ClinVar contains an entry for this variant (Variation ID: 542579). 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 not expected to disrupt RELN protein function with a negative 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.
