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]
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]

Cardiac arrhythmia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 22, 2023This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 2 of the RANGRF protein (p.Glu2Gly). This variant is present in population databases (rs763301510, gnomAD 0.0009%). This missense change has been observed in individual(s) with arrhythmia (PMID: 30847666). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
