Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1 PM2 PM5 PP3_Strong

The NM_000176.3(NR3C1):​c.1430G>A​(p.Arg477His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,628 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging 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. R477S) has been classified as Likely pathogenic.

Genes affected

NR3C1 (HGNC:7978): (nuclear receptor subfamily 3 group C member 1) This gene encodes glucocorticoid receptor, which can function both as a transcription factor that binds to glucocorticoid response elements in the promoters of glucocorticoid responsive genes to activate their transcription, and as a regulator of other transcription factors. This receptor is typically found in the cytoplasm, but upon ligand binding, is transported into the nucleus. It is involved in inflammatory responses, cellular proliferation, and differentiation in target tissues. Mutations in this gene are associated with generalized glucocorticoid resistance. Alternative splicing of this gene results in transcript variants encoding either the same or different isoforms. Additional isoforms resulting from the use of alternate in-frame translation initiation sites have also been described, and shown to be functional, displaying diverse cytoplasm-to-nucleus trafficking patterns and distinct transcriptional activities (PMID:15866175).

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a helix (size 10) in uniprot entity GCR_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_000176.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.99

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 477 of the NR3C1 protein (p.Arg477His). This variant is present in population databases (rs104893913, gnomAD 0.0009%). This missense change has been observed in individual(s) with primary cortisol resistance (PMID: 11589680). ClinVar contains an entry for this variant (Variation ID: 16156). 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. Experimental studies have shown that this missense change affects NR3C1 function (PMID: 11589680, 15017388). This variant disrupts the p.Arg477 amino acid residue in NR3C1. Other variant(s) that disrupt this residue have been observed in individuals with NR3C1-related conditions (PMID: 11589680, 27120390, 29444898), which suggests that this may be a clinically significant amino acid residue. 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. -
