Review
Myocardial infarction is rare in children, teenagers and young adults (aged<20 years). The most common aetiologies identified include Kawasaki disease, familial hypercholesterolaemia, collagen vascular disease-induced coronary arteritis, substance abuse (cocaine, glue sniffing), trauma, complications of congenital heart disease surgery, genetic disorders (such as progeria), coronary artery embolism, occult malignancy and several other rare conditions. Nephrotic syndrome is a very rare cause of myocardial infarction, but it is probably underestimated. The purpose of this review was to determine the current state of knowledge on acute coronary syndrome related to nephrotic syndrome. We thus performed a comprehensive structured literature search of the Medline database for articles published between January 1st, 1969 and December 31st, 2021. Myocardial infarction in young adults can be broadly divided into two groups: cases of angiographically normal coronary arteries; and cases of coronary artery disease of varying aetiology. There are several possible mechanisms underlying the association between acute coronary syndrome and nephrotic syndrome: (1) coronary thrombosis related to hypercoagulability and/or platelet hyperactivity; (2) atherosclerosis related to hyperlipidaemia; and (3) drug treatment. All of these mechanisms must be evaluated systematically in the acute phase of disease because they evolve rapidly with the treatment of nephrotic syndrome. In this review, we propose a decision algorithm for the management of acute coronary syndrome in the context of nephrotic syndrome. The final part of the review presents the short- and medium-term therapeutic strategies available. Thromboembolism related to nephrotic syndrome is a rare non-atherosclerotic cause of acute coronary syndrome, and prospective studies are needed to evaluate a systematic approach with personalized therapeutic strategies.

BACKGROUND
Variants in the LMNA gene, encoding lamins A/C, are responsible for a growing number of diseases, all of which complying with the definition of rare diseases. LMNA-related disorders have a varied phenotypic expression with more than 15 syndromes described, belonging to five phenotypic groups: Muscular Dystrophies, Neuropathies, Cardiomyopathies, Lipodystrophies and Progeroid Syndromes. Overlapping phenotypes are also reported. Linking gene and variants with phenotypic expression, disease mechanisms, and corresponding treatments is particularly challenging in laminopathies. Treatment recommendations are limited, and very few are variant-based.
OBJECTIVE
The Treatabolome initiative aims to provide a shareable dataset of existing variant-specific treatment for rare diseases within the Solve-RD EU project. As part of this project, we gathered evidence of specific treatments for laminopathies via a systematic literature review adopting the FAIR (Findable, Accessible, Interoperable, and Reusable) guidelines for scientific data production.
METHODS
Treatments for LMNA-related conditions were systematically collected from MEDLINE and Embase bibliographic databases and clinical trial registries (Cochrane Central Registry of Controlled Trials, clinicaltrial.gov and EudraCT). Two investigators extracted and analyzed the literature data independently. The included papers were assessed using the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence.
RESULTS
From the 4783 selected articles by a systematic approach, we identified 78 papers for our final analysis that corresponded to the profile of data defined in the inclusion and exclusion criteria. These papers include 2 guidelines/consensus papers, 4 meta-analyses, 14 single-arm trials, 15 case series, 13 cohort studies, 21 case reports, 8 expert reviews and 1 expert opinion. The treatments were summarized electronically according to significant phenome-genome associations. The specificity of treatments according to the different laminopathic phenotypical presentations is variable.
CONCLUSIONS
We have extracted Treatabolome-worthy treatment recommendations for patients with different forms of laminopathies based on significant phenome-genome parings. This dataset will be available on the Treatabolome website and, through interoperability, on genetic diagnosis and treatment support tools like the RD-Connect's Genome Phenome Analysis Platform.

Review
The sella turcica is an important anatomical reference used in orthodontics for the evaluation of craniofacial growth. Studies have found variations in the sella turcica morphology in patients with syndromes affecting the craniofacial complex. This review aims to determine whether genetic syndromes involving the craniofacial complex are associated with abnormal radiographic sella turcica morphology and whether there is a pattern of malformation which is consistent within each syndrome. An electronic database search was conducted to identify relevant studies. We included primary studies describing the morphology of the sella turcica on lateral radiographs in human subjects with genetic syndromes involving the craniofacial complex. No restrictions were placed on language or timeframe. PROSPERO registration CRD42019148060. Thirty-eight studies were included in this review. A 'J'-shaped sella was found in patients with Hutchinson-Gilford-Progeria syndrome and other syndromes. A bulbous dorsum sellae was highly prevalent Cleidocranial dysplasia, and a bulbous dorsum sellae and uneven contours of the clivus was found in Cri du chat syndrome. A steep clivus was described in patients with Axenfeld-Rieger syndrome. An oblique anterior wall was the most frequent malformation found in Down's syndrome. Genetic syndromes affecting the craniofacial complex are associated with abnormal morphology of the radiographic sella turcica. Clinicians should be observant of abnormal sella turcica morphology which can be a sign of undiagnosed or subclinical syndromes. More high-quality studies are needed which use standardized and objective methods of determining the morphology of the sella turcica.
