Genes affected

GFER (HGNC:4236): (growth factor, augmenter of liver regeneration) The hepatotrophic factor designated augmenter of liver regeneration (ALR) is thought to be one of the factors responsible for the extraordinary regenerative capacity of mammalian liver. It has also been called hepatic regenerative stimulation substance (HSS). The gene resides on chromosome 16 in the interval containing the locus for polycystic kidney disease (PKD1). The putative gene product is 42% similar to the scERV1 protein of yeast. The yeast scERV1 gene had been found to be essential for oxidative phosphorylation, the maintenance of mitochondrial genomes, and the cell division cycle. The human gene is both the structural and functional homolog of the yeast scERV1 gene. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitter	clinical testing	Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	May 25, 2020	A heterozygous missense variant was identified, NM_005262.2(GFER):c.586C>T in exon 3 of 3 of the GFER gene. This substitution is predicted to create a major amino acid change from an arginine to a cysteine at position 196 of the protein; NP_005253.3(GFER):p.(Arg196Cys). The arginine at this position has high conservation (100 vertebrates, UCSC), and is located within the Erv1 / Alr family domain (NCBI, PDB). In silico software predicts this variant to be damaging (PolyPhen2, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD population database at a global population frequency of 0.004% (10 heterozygotes; 0 homozygotes) with a Latino sub-population frequency of 0.008%. An alternative residue change to histidine at the same location has also been reported in the gnomAD database at a frequency of 0.01%. This variant has been previously reported as pathogenic in a patient with mitochondrial disease (ClinVar, Martikainen, M. et al. (2017)). Based on information available at the time of curation, this variant has been classified as a VUS with POTENTIAL CLINICAL RELEVANCE. -
