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 15 ACMG points.

PM1
In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 1 uncertain in NM_000104.4
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, 0.966
PP5
Variant 2-38071195-C-T is Pathogenic according to our data. Variant chr2-38071195-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 7735.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
