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 Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a chain Uroporphyrinogen-III synthase (size 264) in uniprot entity HEM4_HUMAN there are 8 pathogenic changes around while only 1 benign (89%) in NM_000375.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.981
• PP5: Variant 10-125815120-G-A is Pathogenic according to our data. Variant chr10-125815120-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 3751.Status of the report is no_assertion_criteria_provided, 0 stars.
