Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_020631.6(PLEKHG5):c.2390C>T(p.Thr797Met) variant causes a missense change. The variant allele was found at a frequency of 0.000049 in 1,612,936 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. T797T) has been classified as Likely benign.

Submissions by phenotype
not provided Uncertain:2
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
- -
Charcot-Marie-Tooth disease recessive intermediate C Uncertain:1
This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
Inborn genetic diseases Uncertain:1
The c.2390C>T (p.T797M) alteration is located in exon 20 (coding exon 19) of the PLEKHG5 gene. This alteration results from a C to T substitution at nucleotide position 2390, causing the threonine (T) at amino acid position 797 to be replaced by a methionine (M). 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 threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 797 of the PLEKHG5 protein (p.Thr797Met). This variant is present in population databases (rs111724922, gnomAD 0.02%). 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: 468907). 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: "Tolerated"; 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. -
