Summary

Leber congenital amaurosis (MONDO:0018998) is a disease (an umbrella term covering 21 Mondo subtypes) caused by variants in PRPH2, CCT2, and LRAT, with 67 cohort genes and 22 clinical trials. The dominant Reactome pathway is Inactivation, recovery and regulation of the phototransduction cascade (6 cohort genes). Top therapeutic interventions include voretigene neparvovec, polymyxin b, and trimethoprim.

Pharmacogenomics

Cohort genes with a PharmGKB record: 66; with CPIC/DPWG dosing guidelines: 0.

No cohort gene has a CPIC/DPWG genotype-guided dosing guideline (PharmGKB).

Chemical tractability of cohort targets

17 approved/phased compounds have measured bioactivity against a cohort gene (and aren’t yet in disease-level trials). This is a research / tractability signal, NOT a therapeutic recommendation — a bioactivity row often reflects off-target or screening binding (e.g. promiscuous kinase inhibitors against a cohort kinase), implying no disease mechanism.
