1. Sudden death of a four-day-old newborn due to mitochondrial trifunctional protein/long-chain 3-hydroxyacyl-coa dehydrogenase deficiencies and a systematic literature review of early deaths of neonates with fatty acid oxidation disordersAna Drole Torkar, Ana Klinc, Žiga Iztok Remec, Branislava Ranković, Klara Bartolj, Sara Bertok, Sara Colja, Vanja Čuk, Maruša Debeljak, Eva Kozjek, Barbka Repič-Lampret, Matej Mlinarič, Tinka Mohar Hajnšek, Daša Perko, Katarina Štajer, Tine Tesovnik, Domen Trampuž, Blanka Ulaga, Jernej Kovač, Tadej Battelino, Mojca Žerjav-Tanšek, Urh Grošelj, 2025, pregledni znanstveni članek Povzetek: Mitochondrial trifunctional protein (MTP) and long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiencies have been a part of the Slovenian newborn screening (NBS) program since 2018. We describe a case of early lethal presentation of MTPD/LCHADD in a term newborn. The girl was born after an uneventful pregnancy and delivery, and she was discharged home at the age of 3 days, appearing well. At the age of 4 days, she was found without signs of life. Resuscitation was not successful. The NBS test performed using tandem mass spectrometry (MS/MS) showed a positive screen for MTPD/LCHADD. Genetic analysis performed on a dried blood spot (DBS) sample identified two heterozygous variants in the HADHA gene: a nucleotide duplication introducing a premature termination codon (p.Arg205Ter) and a nucleotide substitution (p.Glu510Gln). Post-mortem studies showed massive macro-vesicular fat accumulation in the liver and, to a smaller extent, in the heart, consistent with MTPD/LCHADD. A neonatal acute cardiac presentation resulting in demise was suspected. We conducted a systematic literature review of early neonatal deaths within 14 days postpartum attributed to confirmed fatty acid oxidation disorders (FAODs), which are estimated to account for 5% of sudden infant deaths. We discuss the pitfalls of the NBS for MTPD/LCHADD.

2. Gene therapy of rare diseases as a milestone in medicine : overview of the field and report on initial experiences in SloveniaUrh Grošelj, Marko Kavčič, Ana Drole Torkar, Jan Kafol, Duško Lainšček, Roman Jerala, Matjaž Sever, Samo Zver, Gregor Serša, Maja Čemažar, Primož Strojan, Aleš Grošelj, Mojca Žerjav-Tanšek, Špela Miroševič, Simona Ivančan, Tomaž Prelog, David Gosar, Jasna Oražem, Matej Mlinarič, Sara Bertok, Jernej Kovač, Jana Kodrič, Saba Battelino, Marko Pokorn, Alojz Ihan, Janez Jazbec, Tadej Battelino, Damjan Osredkar, 2025, pregledni znanstveni članek Povzetek: Gene therapy has transitioned from a long-awaited promise to a clinical reality, offering transformative treatments for rare congenital diseases and certain cancers, which have a significant impact on patients’ lives. Current approaches focus on gene replacement therapy, either in vivo or ex vivo, mostly utilizing viral vectors to deliver therapeutic genes into target cells. However, refining these techniques is essential to overcome challenges and complications associated with gene therapy to ensure long-term safety and efficacy. Slovenia has witnessed significant advancements in this field since 2018, marked by successful gene therapy trials and treatments for various rare diseases. Significant strides have been made in the field of gene therapy in Slovenia, treating patients with spinal muscular atrophy and rare metabolic disorders, including the pioneering work on CTNNB1 syndrome. Additionally, immune gene therapy, exemplified by IL-12 adjuvant therapy for cancer, has been a focus of research in Slovenia. Through patient-centred initiatives and international collaborations, researchers in Slovenia are advancing preclinical research and clinical trials, paving the way for accessible gene therapies. Establishing clinical infrastructure and genomic diagnostics for rare diseases is crucial for gene therapy implementation. Efforts in this regard in Slovenia, including the establishment of a Centre for Rare Diseases, Centre for the Technologies of Gene and Cell Therapy, and rapid genomic diagnostics, demonstrate a commitment to comprehensive patient care. Despite the promises of gene therapy, challenges remain, including cost, distribution, efficacy, and long-term safety. Collaborative efforts are essential to address these challenges and ensure equitable access to innovative therapies for patients with rare diseases.
