Inborn genetic diseases Uncertain:1
The c.1783G>C (p.E595Q) alteration is located in exon 16 (coding exon 15) of the PLEKHG5 gene. This alteration results from a G to C substitution at nucleotide position 1783, causing the glutamic acid (E) at amino acid position 595 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Neuronopathy, distal hereditary motor, autosomal recessive 4;C3809309:Charcot-Marie-Tooth disease recessive intermediate C Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 595 of the PLEKHG5 protein (p.Glu595Gln). This variant is present in population databases (rs140597591, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with PLEKHG5-related conditions. ClinVar contains an entry for this variant (Variation ID: 546263). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
not provided Uncertain:1
The E595Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The E595Q variant is observed in 15/24014 (0.06%) alleles from individuals of African background in large population cohorts (Lek et al., 2016). The E595Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
