Position:

• chr1-6473051-C-CGTCTTCA

Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1 PM2 PP5

The NM_020631.6(PLEKHG5):​c.912_918dupTGAAGAC​(p.Glu307fs) variant causes a frameshift, stop gained change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. D306D) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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.
