ABCD3 (ATP binding cassette subfamily D member 3), also called PMP70, is named by 1 disorder entry.
In the ai-gene-review snapshot the KB ingests, ABCD3's core molecular functions are ATPase-coupled transmembrane transporter activity; fatty acyl-CoA hydrolase activity; and long-chain fatty acid transmembrane transporter activity, at the peroxisomal membrane. The upstream review is being updated to use the more specific ABC-type fatty-acyl-CoA transporter term, which is the term the KB binds.
The one entry types ABCD3 as causative: Congenital Bile Acid Synthesis Defect 5, with a germline variant origin and a functional impact of loss of function. ABCD3 sits on the node ABCD3 Loss of Function. ClinGen rates the relationship only limited, below the Definitive or Strong tier that a causative typing implies.
The KB process on ABCD3's own node is peroxisome organization, recorded as abnormal, while the import and bile-acid processes sit on downstream nodes; the exact-identifier overlap with ai-gene-review core processes is therefore 0.
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 IN_PROGRESS; 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.
