Inborn Errors of Metabolism

Inborn Errors of Metabolism

Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Area of Science:

Pediatric Endocrinology
Computational Health Science
Machine Learning in Medicine

Background:

Childhood metabolic diseases, including prediabetes, type 2 diabetes (T2D), and metabolic syndrome, are rising globally.
These conditions significantly impair quality of life and increase the risk of chronic comorbidities.
Effective early detection tools are urgently needed for timely intervention in pediatric populations.

Purpose of the Study:

To develop and validate an interpretable deep learning model for predicting the onset of prediabetes, T2D, and metabolic syndrome in children.
To assess the utility of longitudinal clinical data, including body mass index (BMI) trajectories, for improving predictive accuracy.

Main Methods:

Utilized interpretable deep learning on electronic health record data from a large integrated health system.
Included longitudinal clinical measurements, demographical data, and diagnosis codes for a cohort of 49,517 children (aged 2-18) with overweight or obesity.
Compared model performance using longitudinal data versus models relying solely on the most recent BMI data.

Main Results:

The model achieved area under the receiver operating characteristic curve (AUC) accuracies of up to 0.87 for T2D, 0.79 for metabolic syndrome, and 0.79 for prediabetes.
Incorporating longitudinal data significantly improved AUCs by 11-13% compared to models using only the most recent BMI.
BMI trajectories were identified as a consistently influential feature in the predictive model.

Conclusions:

Longitudinal data analysis, specifically BMI trajectories, provides a more comprehensive patient health characterization and enhances predictive accuracy for pediatric metabolic diseases.
Interpretable deep learning models leveraging historical data offer a promising approach for early detection and intervention.
This methodology highlights the importance of considering temporal health trends over static measurements for improved clinical prediction.
