not specified Uncertain:1
The c.205G>A (p.E69K) alteration is located in exon 4 (coding exon 3) of the GAL gene. This alteration results from a G to A substitution at nucleotide position 205, causing the glutamic acid (E) at amino acid position 69 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Familial temporal lobe epilepsy 8 Uncertain:1
This variant is present in population databases (rs571107777, ExAC 0.006%) but has not been reported in the literature in individuals with a GAL-related disease. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces glutamic acid with lysine at codon 69 of the GAL protein (p.Glu69Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine. -
