Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP3_Moderate BS2

The NM_000537.4(REN):​c.1184G>A​(p.Arg395Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000889 in 1,461,836 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R395W) has been classified as Uncertain significance.

Genes affected

REN (HGNC:9958): (renin) This gene encodes renin, an aspartic protease that is secreted by the kidneys. Renin is a part of the renin-angiotensin-aldosterone system involved in regulation of blood pressure, and electrolyte balance. This enzyme catalyzes the first step in the activation pathway of angiotensinogen by cleaving angiotensinogen to form angiotensin I, which is then converted to angiotensin II by angiotensin I converting enzyme. This cascade can result in aldosterone release, narrowing of blood vessels, and increase in blood pressure as angiotension II is a vasoconstrictive peptide. Transcript variants that encode different protein isoforms and that arise from alternative splicing and the use of alternative promoters have been described, but their full-length nature has not been determined. Mutations in this gene have been shown to cause hyperuricemic nephropathy familial juvenile 2, familial hyperproreninemia, and renal tubular dysgenesis. [provided by RefSeq, May 2020]

Familial juvenile hyperuricemic nephropathy type 2 Uncertain:1

Oct 10, 2023

Institute for Human Genetics and Genomic Medicine, Uniklinik RWTH Aachen

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The detected change is not reported in the general population (gnomAD) (as of October 10, 2023). It has not yet been described in the ClinVar database or in the literature. From a bioinformatic perspective, the change is inconsistently classified as disease-causing (CADDphred 28.4, PolyPhen2), but also as “tolerated” and “benign” (SIFT, MutationTaster). The variant is currently considered a “variant of uncertain clinical significance” (ACMG criteria). -
