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.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 26, 2021 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with PLEKHG5-related conditions. This variant is present in population databases (rs760122001, ExAC 0.002%). This sequence change creates a premature translational stop signal (p.Glu580*) in the PLEKHG5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PLEKHG5 are known to be pathogenic (PMID: 17564964). - |
