Variant summary

Our verdict is Pathogenic. The variant received 17 ACMG points: 17P and 0B. PM1PM5PP2PP3_StrongPP5_Very_Strong

The NM_000104.4(CYP1B1):​c.1168C>T​(p.Arg390Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000397 in 1,613,650 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R390S) has been classified as Pathogenic.

Genes affected
CYP1B1 (HGNC:2597): (cytochrome P450 family 1 subfamily B member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The enzyme encoded by this gene localizes to the endoplasmic reticulum and metabolizes procarcinogens such as polycyclic aromatic hydrocarbons and 17beta-estradiol. Mutations in this gene have been associated with primary congenital glaucoma; therefore it is thought that the enzyme also metabolizes a signaling molecule involved in eye development, possibly a steroid.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 17 ACMG points.

PM1
In a helix (size 13) in uniprot entity CP1B1_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_000104.4
PM5
Other missense variant is known to change same aminoacid residue: Variant chr2-38071186-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 2203048.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 35 curated pathogenic missense variants (we use a threshold of 10). The gene has 9 curated benign missense variants. Trascript score misZ: -2.0997 (below the threshold of 3.09). GenCC associations: The gene is linked to Peters anomaly, anterior segment dysgenesis 6, glaucoma 3A, CYP1B1-related glaucoma with or without anterior segment dysgenesis, congenital glaucoma.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.967
PP5
Variant 2-38071186-G-A is Pathogenic according to our data. Variant chr2-38071186-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 335952.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
