Relationship is the entry's genetic[].relationship_type. untyped means the entry has a genetic record for the gene but does not type it; its free-text association is shown instead.
| Disorder | Relationship | Where the gene appears |
|---|---|---|
| Blue Cone Monochromacy | causative loss of function |
mechanism: Loss of Function of the OPN1LW/OPN1MW Opsin Gene Array
|
| Protan Color Vision Deficiency | no genetic record germline loss of function |
mechanism: Unequal Recombination in the Xq28 L/M Opsin Gene Array

An entry matches when ClinGen's MONDO disease is the entry's own disease term, a subtype term, or an exact-match mapping. An amber status marks an entry ClinGen supports the gene for (Definitive, Strong or Moderate) whose own record does not type it. A Limited, Disputed or Refuted tier on such an entry is not a gap.
