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]

This variant has not been reported in the literature in individuals with RANGRF-related conditions. 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant is not present in population databases (ExAC no frequency). This sequence change affects the initiator methionine of the RANGRF mRNA. The next in-frame methionine is located at codon 20. -
