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 testingInvitaeSep 26, 2018In 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PLEKHG5-related disease. This variant is present in population databases (rs776271244, ExAC 0.006%). This sequence change replaces proline with leucine at codon 13 of the PLEKHG5 protein (p.Pro13Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. -
