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.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.S855L variant (also known as c.2564C>T), located in coding exon 19 of the PLEKHG5 gene, results from a C to T substitution at nucleotide position 2564. The serine at codon 855 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Labcorp Genetics (formerly Invitae), Labcorp
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 855 of the PLEKHG5 protein (p.Ser855Leu). This variant is present in population databases (rs768995193, gnomAD 0.007%). 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: 195528). 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. -
