Component
Human biallelic pathogenic PANK2 genotypes
Study-defined composite of biallelic disease-associated PANK2 allele/genotype states from the 2001 gene-discovery study. This is not the canonical PANK2 gene or its protein; variant details were not enumerated in the abstract. Canonical gene node: pank2-gene.

How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What it acts on
The gene-discovery study identified recessive PANK2 defects as the cause of the studied inherited neurodegeneration with brain iron accumulation.
