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]

Benign:4

Benign, no assertion criteria provided	clinical testing	Clinical Genetics, Academic Medical Center	-	- -
Benign, criteria provided, single submitter	clinical testing	GeneDx	May 10, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Sep 16, 2024	Variant summary: RANGRF c.181G>T (p.Glu61X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, however current evidence is not sufficient to establish loss of function as a mechanism for disease. The variant allele was found at a frequency of 0.0045 in 1606716 control chromosomes in the gnomAD database (v4.1 dataset). , including 29 homozygotes. The observed variant frequency is approximately 700-fold of the estimated maximal expected allele frequency for a pathogenic variant in RANGRF causing Arrhythmia phenotype (6.3e-06). Although the variant was proposed to be related to various phenotypes in the literature, a recent study performing exhaustive genetic interpretation of reported variants in minor genes (potentially) associated with Brugada syndrome, classified the variant as benign (Campuzano_2019). The following publication have been ascertained in the context of this evaluation (PMID: 30821013). ClinVar contains an entry for this variant (Variation ID: 190845). Based on the evidence outlined above, the variant was classified as benign. -
