Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2
The NM_173728.4(ARHGEF15):c.1918G>A(p.Glu640Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000359 in 1,613,588 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E640Q) has been classified as Uncertain significance.

Developmental and epileptic encephalopathy Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 640 of the ARHGEF15 protein (p.Glu640Lys). This variant is present in population databases (rs375563358, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with ARHGEF15-related conditions. ClinVar contains an entry for this variant (Variation ID: 572173). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
