Cardiovascular aspects of Noonan syndrome and related disorders.
Noonan syndrome and other RASopathies constitute an important group of disorders to be considered in the differential diagnosis in individuals with congenital heart defects and hypertrophic cardiomyopathy. The cardiovascular phenotype of RASopathies is complex and comprises a spectrum of abnormalities, including not only congenital defects but also abnormalities affecting the lymphovascular system and other anomalies of the vascular system, which may emerge over the course of an individual's lifetime. Affected individuals typically present with a syndromic phenotype, exhibiting additional physical symptoms outside of the cardiovascular system and neuropsychological deficits. Genetic testing of the established disease genes for RASopathies is an effective method for identifying the underlying genetic variant in the majority of cases. This approach is strongly recommended to facilitate a more precise prognosis and the potential for personalized targeted therapies. Screening for RASopathy-associated gene variants in individuals with isolated CHDs, HCM, or other isolated cardiovascular features outside the NS spectrum appears to have limited clinical utility. However, it should be noted that the RASopathy phenotype may be challenging to discern in cases of mild or oligosymptomatic involvement, or it may be obscured by the presence of severe medical conditions, particularly in very young children.
期刊介绍:
medizinischegenetik is a scientific journal that is owned and published by the German Society of Human Genetics e.V. since 1989. The journal was founded by Prof. Jan Murken, München. Self-published until 2006, from 2007-2019 published at Springer Verlag and since 2020 at De Gruyter.
medizinischegenetik serves education and training among colleagues, the interdisciplinary exchange of knowledge in all areas of human genetics in clinics, practice, research and teaching. Each issue of the quarterly journal deals with a focus that provides a comprehensive overview of current developments in specific clinical pictures, technical developments and therapeutic approaches. All reviews are written in English language. The journal thus creates a platform for the international exchange of knowledge and increased awareness of German research activities in the scientific community.
In addition, medizinischegenetik contains information on activities in its own subject in the German-language section. This includes conference reports, association announcements, personnel matters, statements and guidelines. With health policy questions, historical retrospectives and comments on current developments, the profession takes a stand on human genetic issues in Germany, Austria and Switzerland.
