CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase) is named by 1 disorder entry.
ai-gene-review gives CAD's core molecular functions as aspartate carbamoyltransferase activity; carbamoyl-phosphate synthase (glutamine-hydrolyzing) activity; and dihydroorotase activity, the first three steps of de novo pyrimidine synthesis carried on one polypeptide, acting in 'de novo' UMP biosynthetic process; and 'de novo' pyrimidine nucleobase biosynthetic process.
The one entry that names CAD, Developmental and Epileptic Encephalopathy 50, types it causative with a germline origin. ClinGen rates the gene definitive for this disease. The gene sits on the node Biallelic CAD Loss of Function, which marks all three of the catalytic activities above as decreased.
The pyrimidine-synthesis process terms sit on a downstream node that does not itself name CAD, so the gene's own nodes share 0 process terms with ai-gene-review by identifier, although the molecular functions agree term for term.
Underlined values are claims re-computed from the knowledge base each time this page is built. The tables below are the source of truth.
ai-gene-review has this gene at status INITIALIZED; the description is shown only once the review is complete. Read the draft upstream.
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.

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.
