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 Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 9 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-124482935-G-GTCAAGCAGGGCGGCGTTGGCCTTCTCCTGAGCGTCTT is Pathogenic according to our data. Variant chr9-124482935-G-GTCAAGCAGGGCGGCGTTGGCCTTCTCCTGAGCGTCTT is described in ClinVar as [Pathogenic]. Clinvar id is 817717.Status of the report is criteria_provided_single_submitter, 1 stars.

The c.1172_1208dup37 variant in the NR5A1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The c.1172_1208dup37 variant causes a frameshift starting with codon Aspartic Acid 403, changes this amino acid to a Glutamic Acid residue, and creates a premature Stop codon at position 13 of the new reading frame, denoted p.Asp403GlufsX13. This variant is predicted to cause loss of normal protein function through protein truncation. The c.1172_1208dup37 variant is not observed in large population cohorts (Lek et al., 2016). We interpret c.1172_1208dup37 as a pathogenic variant. -
