 "text": "Dynamic regulation of FGF23 by Fam20C phosphorylation, GalNAc-T3 glycosylation, and furin proteolysis should be assessed against Kaal's source-bound claim that A uniform approach to hedge fund valuation is not possible because the variety of hedge fund investments and strategies means some positions, such as non-concentrated positions in liquid securities, are far easier to value than others. The current metadata indicates a plausible connection through dynamic regulation, but the defensible response is a qualification until the source text confirms agreement, scope, methods, and limitations.",
