The variant allele was found at a frequency of 0.189 in 151,994 control chromosomes in the GnomAD database, including 3,240 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.19 (3240 hom., cov: 32)
• Consequence: SRD5A1 NM_001047.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.62

Genes affected

SRD5A1 (HGNC:11284): (steroid 5 alpha-reductase 1) Steroid 5-alpha-reductase (EC 1.3.99.5) catalyzes the conversion of testosterone into the more potent androgen, dihydrotestosterone (DHT). Also see SRD5A2 (MIM 607306).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.468 is higher than 0.05.
