Genes affected

GLE1 (HGNC:4315): (GLE1 RNA export mediator) This gene encodes a predicted 75-kDa polypeptide with high sequence and structure homology to yeast Gle1p, which is nuclear protein with a leucine-rich nuclear export sequence essential for poly(A)+RNA export. Inhibition of human GLE1L by microinjection of antibodies against GLE1L in HeLa cells resulted in inhibition of poly(A)+RNA export. Immunoflourescence studies show that GLE1L is localized at the nuclear pore complexes. This localization suggests that GLE1L may act at a terminal step in the export of mature RNA messages to the cytoplasm. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 12 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-128504900-GC-G is Pathogenic according to our data. Variant chr9-128504900-GC-G is described in ClinVar as [Pathogenic]. Clinvar id is 1362319.Status of the report is criteria_provided_single_submitter, 1 stars.

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1362319). This sequence change creates a premature translational stop signal (p.Glu33Argfs*4) in the GLE1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GLE1 are known to be pathogenic (PMID: 18204449, 24243016, 27684565). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GLE1-related conditions. -
