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.

Collection Method:clinical testing

This sequence change replaces alanine with proline at codon 262 of the PLEKHG5 protein (p.Ala262Pro). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and proline. This variant is present in population databases (rs550362834, 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
