Genes affected
PLEKHG5 (HGNC:29105): (pleckstrin homology and RhoGEF domain containing G5) This gene encodes a protein that activates the nuclear factor kappa B (NFKB1) signaling pathway. Mutations in this gene are associated with autosomal recessive distal spinal muscular atrophy. Multiple transcript variants encoding different isoforms have been found for this gene.

Neuronopathy, distal hereditary motor, autosomal recessive 4;C3809309:Charcot-Marie-Tooth disease recessive intermediate C Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 27, 2021This sequence change replaces phenylalanine with serine at codon 830 of the PLEKHG5 protein (p.Phe830Ser). The phenylalanine residue is moderately conserved and there is a large physicochemical difference between phenylalanine and serine. This variant is present in population databases (rs764007395, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with PLEKHG5-related conditions. 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: "Possibly 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. -
