Special Issue Information

Dear Colleagues,

Inherited metabolic diseases (IMDs), also known as inborn errors of metabolism, constitute a group of genetically determined (mostly monogenic) disorders associated with defects in proteins involved in various biochemical processes (pathways). An exact defect in the protein’s structure or its function results from the presence of pathogenic molecular variants (formerly mutations) in protein-coding genes. The diagnosis of IMD is based on the principle of selective screening—if a symptom/cluster of symptoms suggest(s) a (known) metabolic disease, testing for this condition is performed, not necessarily to confirm the suspicion, but also to rule it out. Confirming the clinical diagnosis of IMD often requires highly specialized testing, including biochemical and molecular (genetic) analyses. As pediatricians play the crucial role in the diagnosis and management of IMDs, it is imperative that clinicians do not miss early opportunities for diagnosis.

Young researchers are welcome to present their achievements, and pediatricians to share their experience and insights from their clinical practice. All are invited to present new metabolic disorders identified by various diagnostic techniques. We encourage researchers to describe the advantages of new diagnostic methods as well as the pitfalls of common diagnostic methods of IMDs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diagnostics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Pediatricians play a crucial role in the early diagnosis and management of inherited metabolic diseases (IMDs). The diagnosis of IMD is based on the principle of selective screening, often requiring highly specialized testing, including biochemical and molecular analyses. The aim of this comprehensive review was to provide pediatricians with the usefulness of basic laboratory analyses in diagnostic process of IMD. The abnormal results of basic laboratory analyses were thoroughly discussed in the context of clinical manifestations of IMDs. Easy-to-use algorithms were implemented to ensure an appropriate differential diagnosis. Full article
