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]

The T2656A variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. A single functional study found that T2656A was associated with severely reduced RAN-binding protein 2 E3 ligase activity (Pichler et al. 2004). The T2656A variant is observed in 86/126,622 (0.07%) alleles from individuals of European background, in the ExAC dataset (Lek et al., 2016). The T2656A variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
