Аннотация

BACKGROUND: Aarskog-Scott syndrome (AAS) is a rare condition with multiple congenital anomalies, caused by hemizygote variants in the FGD1 gene. Its description was based mostly on old case reports, in whom a molecular diagnosis was not always available, or on small series. The aim of this study was to better delineate the phenotype and the natural history of AAS and to provide clues for the diagnosis and the management of the patients.

METHODS: Phenotypic characterisation of the largest reported AAS cohort, comprising 111 male patients with proven causative variants in FGD1, through comprehensive analyses of clinical data including congenital anomalies, growth and neurodevelopment. Review of photographs and radiographs by experts in dysmorphology and skeletal disorders.

RESULTS: This study refines the phenotypic spectrum of AAS, with the description of new morphological and radiological features, and refines the prevalence of the features. Short stature is less frequent than previously reported and has a prenatal onset in more than half of the patients. The growth has a specific course with a catch-up during the first decade often leading to low-normal stature in adulthood. Whereas intellectual disability is rare, patients with AAS have a high prevalence of specific learning difficulties and attention hyperactivity disorder. In light of this better knowledge of AAS, we provide management recommendations.

CONCLUSION: A better knowledge of the natural history and phenotypic spectrum of AAS will be helpful for the clinical diagnosis and for the interpretation of FGD1 variants using a retrophenotyping strategy, which is becoming the most common way of diagnosis nowadays. Recommendations for care will improve the management of the patients.
