The variant allele was found at a frequency of 0.41 in 152,068 control chromosomes in the GnomAD database, including 13,162 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 0.41 (13162 hom., cov: 32)
• Consequence: UROS NM_000375.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.0430

Genes affected

UROS (HGNC:12592): (uroporphyrinogen III synthase) The protein encoded by this gene catalyzes the fourth step of porphyrin biosynthesis in the heme biosynthetic pathway. Defects in this gene cause congenital erythropoietic porphyria (Gunther's disease). [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.462 is higher than 0.05.
