Reversible high-fat ketogenic formula-induced hypertriglyceridemia in a child with NALCN mutation on a ketogenic diet: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe ketogenic diet (KD) is an established therapy for drug-resistant epilepsy; however, metabolic complications such as hyperlipidemia may limit its use. Epilepsy associated with NALCN mutations is rare, and data regarding the efficacy and safety of KD in this population remain limited.
methodsWe report the case of a 7-year-old boy with developmental and epileptic encephalopathy caused by a novel homozygous nonsense NALCN variant (NM_052867.2; c.2524 C > T, p.Arg842*).
resultsInitiation of a classic 3:1 KD using a high-fat ketogenic formula resulted in a marked reduction in seizure frequency and improvement in developmental status. However, severe hypertriglyceridemia developed within weeks (triglycerides up to 1580 mg/dL), necessitating dietary modification. This case highlights reversible, formula-induced hypertriglyceridemia in a child with NALCN-related epilepsy receiving a classic KD.
conclusionsKD can be effective in NALCN channelopathies. Nevertheless, personalized dietary modification, favoring MCTs or monounsaturated fats over saturated long-chain triglycerides, and careful monitoring of the lipid profile are essential to ensure metabolic safety and long-term treatment sustainability.
