Trial summary

Inborn Errors of metabolism comprise a large number of rare conditions with a collective incidence of around 1/2000 newborns. Many disorders are treatable provided that a correct diagnosis can be established in time, and for many diseases novel therapies are being developed. Read more about this study

About this study

Official title: Genetisk Diagnostik Vid medfödda Metabola Sjukdomar

Inborn Errors of metabolism comprise a large number of rare conditions with a collective incidence of around 1/2000 newborns. Many disorders are treatable provided that a correct diagnosis can be established in time, and for many diseases novel therapies are being developed. Without treatment, many of the conditions result in early death or severe irreversible handicaps.

The Centre for Inherited Metabolic Diseases, CMMS at Karolinska university hospital, is an integrated expert center where clinical specialists work closely together with experts in laboratory medicine, combining clinical genetics, clinical chemistry, pediatrics, neurology, and endocrinology. The center serves the whole Swedish population with diagnostics and expert advice on IEM and has a broad arsenal of biochemical investigations designed to detect defects in intermediary metabolism.

Read the detailed description

Approximately one in two thousand infants is born with a metabolic disorder that often leads to brain damage. By means of high-tech genetic mapping using whole genome sequencing (WGS), the investigators have discovered the molecular foundations for several of these diseases.

For investigation of mitochondrial diseases, mitochondria are isolated from muscle biopsies for analysis of ATP production using a range of substrate combinations, determination of activities of respiratory chain complexes, and analysis of nuclear and mitochondrial DNA.

The center also performs the national neonatal screening program, currently comprising 26 treatable diseases. Dried blood spot samples (DBS) are stored in the phenylketonuria (PKU) biobank, currently (2026) holding around 5 million of Sweden's 10.6 million inhabitants.

Many metabolic disorders, however, lack effective counter-measures.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Genetic variant identification using NGS for diagnosis

    Variant identification in participants investigated at the investigators' clinic, the Centre for Inherited Metabolic Diseases, is an ongoing clinical activity. In many cases where no variant is identified by NGS (next-generation sequencing) using WGS, additional methods are applied, including transcriptomics, proteomics, and various cellular models. More than 400 participants are investigated annually with NGS/WGS at the investigators' clinic.

    Measured: Through study completion, an average of 1 year.
