Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1 PM2 PP5

The NM_004959.5(NR5A1):​c.390del​(p.Pro131ArgfsTer165) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. P130P) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

• Conservation: PhyloP100: -5.91

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 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-124500569-GC-G is Pathogenic according to our data. Variant chr9-124500569-GC-G is described in ClinVar as [Pathogenic]. Clinvar id is 12807.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr9-124500569-GC-G is described in Lovd as [Likely_pathogenic]. Variant chr9-124500569-GC-G is described in Lovd as [Pathogenic].
