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]

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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 1933573). This variant has not been reported in the literature in individuals affected with GFER-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 12 of the GFER protein (p.Gly12Ala). -
