Genes affected

RANBP2 (HGNC:9848): (RAN binding protein 2) RAN is a small GTP-binding protein of the RAS superfamily that is associated with the nuclear membrane and is thought to control a variety of cellular functions through its interactions with other proteins. This gene encodes a very large RAN-binding protein that immunolocalizes to the nuclear pore complex. The protein is a giant scaffold and mosaic cyclophilin-related nucleoporin implicated in the Ran-GTPase cycle. The encoded protein directly interacts with the E2 enzyme UBC9 and strongly enhances SUMO1 transfer from UBC9 to the SUMO1 target SP100. These findings place sumoylation at the cytoplasmic filaments of the nuclear pore complex and suggest that, for some substrates, modification and nuclear import are linked events. This gene is partially duplicated in a gene cluster that lies in a hot spot for recombination on chromosome 2q. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RANBP2. . Gene score misZ -0.77637 (greater than the threshold 3.09). Trascript score misZ 3.8106 (greater than threshold 3.09). GenCC has associacion of gene with Leigh syndrome, familial acute necrotizing encephalopathy.

BP4

Computational evidence support a benign effect (MetaRNN=0.0134471655).

BP6

Variant 2-108751977-G-A is Benign according to our data. Variant chr2-108751977-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 469430.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
