Genes affected

RANGRF (HGNC:17679): (RAN guanine nucleotide release factor) This gene encodes a protein that has been shown to function as a guanine nucleotide release factor in mouse and to regulate the expression and function of the Nav1.5 cardiac sodium channel in human. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2010]

RANGRF links:

SLC25A35 (HGNC:31921): (solute carrier family 25 member 35) SLC25A35 belongs to the SLC25 family of mitochondrial carrier proteins (Haitina et al., 2006 [PubMed 16949250]).[supplied by OMIM, Mar 2008]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant has not been reported in the literature in individuals affected with RANGRF-related conditions. This variant is present in population databases (rs752068609, gnomAD 0.002%). This sequence change creates a premature translational stop signal (p.Asp6Leufs*18) in the RANGRF gene. It is expected to result in an absent or disrupted protein product. However, the current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in RANGRF cause disease. -
