Variant summary

Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM2 PM5 PP3_Strong PP5_Very_Strong

The NM_004959.5(NR5A1):​c.937C>T​(p.Arg313Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,459,002 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 Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R313H) has been classified as Pathogenic.

Genes affected

NR5A1 (HGNC:7983): (nuclear receptor subfamily 5 group A member 1) The protein encoded by this gene is a transcriptional activator involved in sex determination. The encoded protein binds DNA as a monomer. Defects in this gene are a cause of XY sex reversal with or without adrenal failure as well as adrenocortical insufficiency without ovarian defect.

ACMG classification

Verdict is Pathogenic. Variant got 16 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr9-124493082-C-T is described in Lovd as [Pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.953
• PP5: Variant 9-124493083-G-A is Pathogenic according to our data. Variant chr9-124493083-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 372437.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr9-124493083-G-A is described in Lovd as [Pathogenic]. Variant chr9-124493083-G-A is described in Lovd as [Likely_pathogenic].

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 313 of the NR5A1 protein (p.Arg313Cys). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 372437). This missense change has been observed in individual(s) with autosomal dominant disorders of sex development (DSD) (PMID: 25122490, 27169744, 30425642). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects NR5A1 function (PMID: 22028768, 25122490, 27169744). -
