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 submitterclinical testingInvitaeDec 27, 2023This sequence change creates a premature translational stop signal (p.Leu789Glnfs*12) 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, 23777631). This variant is present in population databases (rs759212541, gnomAD 0.004%). 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: 468906). For these reasons, this variant has been classified as Pathogenic. -
