Every year, thousands of people die or suffer chronic disability as the result of inherited diseases of the cardiovascular system. In many cases, diagnosis of inherited disease is delayed or missed owing to a lack of awareness, and an even greater number of relatives are exposed to unnecessary risk. This new edition of Inherited Cardiac Disease provides a comprehensive summary of the aetiology, presentation, and management of genetic disorders of the cardiovascular system. Fully updated to reflect the advances in molecular genetic technologies and the publication of national guidelines for the management of families with inherited cardiac diseases, it retains the first edition’s broad scope and applicability to all members of the multidisciplinary team, from specialists in cardiology and clinical genetics, to genetic counsellors, paediatricians, nurse specialists, and GPs who may come into contact with families presenting with inherited cardiac diseases. After chapters on the general principles of cardiovascular genetics, genetic testing and counselling, individual disorders are then examined in detail, each account featuring a clinical summary, diagnostic tests and special investigations, and treatments relevant to each inherited cardiac disease. Written in the succinct bullet-point style of the Oxford Specialist Handbooks, this new edition of Inherited Cardiac Disease delivers key information in an accessible manner, and is an invaluable guide to anyone who works with patients who are affected by inherited diseases of the cardiovascular system in their practice.

AbstractThe Human Genetics Society of Australasia is a vibrant professional society with more than 900 members that promotes and regulates the practice of human and medical genetics in Australia and New Zealand. The growth of human genetics was stimulated by the development of diagnostic clinical cytogenetics laboratories in the early to mid 1960s. This coincided with the recognition by medical specialists, mainly pediatricians, that genetic disorders, especially inborn errors of metabolism and birth defects, were of clinical interest and potentially challenging areas for their skills. The organization of professionals in human genetics was slow to evolve. There was an early Western Australian Human Genetics Society, and the cytogenetics community had begun to meet annually from about 1966 but was coordinated by a mailing list rather than as a formal organization. In 1976, as part of the celebrations of the Centenary Year of the Adelaide Children's Hospital, a clinical genetics meeting involving several high profile international speakers and most of the senior medical geneticists in Australia and New Zealand along with the annual meeting of the loose-knit cytogeneticists group agreed that a small working group be charged with setting up a Human Genetics Society. The society was formally incorporated in South Australia in 1977.

1. Abstract 1.1. Background: Cherubism is a very rare, mostly a childhood condition that can be horribly disfiguring. We have previously reported our extensive experiences with the diagnosis of rare genetic disorders in a plethora of publications. We have previously reported a large number of rare conditions in Iraq and we have also helped physicians in the diagnosis and publication of rare syndromes observed in other countries. The aim of this papers is to help physicians in advancing the diagnostic skills in the field of clinical genetics by reviewing briefly a rare syndrome that have not been reported in Iraq, but it is associated with certain clinical characteristics that allow an early diagnosis when seen for the first time. 1.2. Patients and methods: During the last week of January, 2021, several TV channels presented and discussed the problem of two brothers from Egypt who were considered to have a very rare poorly defined condition that has been associated with progressive disfigurement which resulted in embarrassing social encounters. The cases of the two brothers are presented. 1.3. Results: The older brother aged 15 and the younger brother aged 14 years. Both had abnormal bilateral and symmetric growth of the jaw resulting in a wide jaw appearance and a round and swollen appearance of cheeks. They also had no teeth on the lower jaw and loose or misplaced teeth on the upper jaw. The parents and a third brother were unaffected. Both children didn’t have mental retardation. The older brother had more severe disfigurement and many people were asking him to remove the mask he is wearing. He also had very poor vision of left eye resulting from the pressure effect and upward displacement of the eye. The younger brother had a surgical operation to remove a benign tumor from the lower jaw which reduced his disfigurement. Conclusion: Awareness of doctors with this condition “Cherubism” is helpful and denosumab can be tried in severe cases based on the evidence provided by Bar Droma, et al (2020).

AbstractGenetics has traditionally enabled the reliable diagnosis of patients with rare genetic disorders, thus empowering the key role of today’s clinical geneticists in providing healthcare. With the many novel technologies that have expanded the genetic toolkit, genetics is increasingly evolving beyond rare disease diagnostics. When placed in a transition context—like we do here—clinical genetics is likely to become a fully integral part of future healthcare and clinical genetic expertise will be required increasingly outside traditional clinical genetic settings. We explore transition effects on the thinking (culture), organizing (structure), and performing (practice) in clinical genetics, taking genetic healthcare in Estonia, Finland, and the Netherlands as examples. Despite clearly distinct healthcare histories, all three countries have initially implemented genetic healthcare in a rather similar fashion: as a diagnostic tool for predominantly rare congenital diseases, with clinical geneticists as the main providers. Dynamics at different levels, such as emerging technologies, biobanks and data infrastructure, and legislative frameworks, may require development of a new system attuned with the demands and (historic) context of specific countries. Here, we provide an overview of genetic service provisions in Estonia, Finland, and the Netherlands to consider the impact of historic and recent events on prospective developments in genetic healthcare.

In recent years we have observed a technological revolution in genetics. For years molecular diagnostics in genetic disorders were limited to a single gene or to a group of genes. The technological breakdown in molecular genetics relies on the change of perspective from the analysis of a single gene to the whole genome sequencing (WGS) or whole-exome sequencing (WES). The exome is defined as a coding part of the genome consisting of the coding parts (exons) of all genes. Thus, at present geneticists have access to the whole genome instead of separate/selected genes. Clinical genetics in the era of genomic sequencing has to cope with new challenges concerning the confidentiality of genetic data, genetic discrimination, genetic and clinical determinism, or incidental findings detected in genome analysis. This short review attempts to demonstrate the ethical challenges faced in the era of genome sequencing.

Most genetic disorders present in early childhood, some even in utero. The diagnosis and management of genetic disorders is, therefore, an important part of fetal medicine and pediatrics, including pediatric dentistry. Clinical genetics, which traditionally is responsible for genetic counseling, is an important collaborator. This article summarises the recent findings in genetics and elaborates on its benefits as well.

Abstract Background: We have previously described our extensive experiences with clinical genetic and dysmorphology in a plethora of publications. In a previous study, we reported 43 children with uncommon, rare and very rare genetic and hereditary disorders whom were observed during three-year period (2016-2018). In that series, very rare genetic, the case number 104 of Sanjad-Sakati-Richardson-Kirk syndrome in the world, the case number 130 of Townes Brocks syndrome and the case number 170 of Coffin Siris syndrome in the world. The aim of this paper is to describe our 2019 extraordinary new experiences with genetic disorders and dysmorphic syndromes. Material and methods: During the year 2019, 37 patients (25 males and 12 female) with genetic disorders and dysmorphic syndromes and were studied at the Children Teaching Hospital of Baghdad Medical City. Their ages ranged from 2 days to sixteen years. Results: Eight patients had Down syndrome (6 boys and 2 girls), 5 patients had Cornelia De Lang syndrome (4 boys and one girl), 2 male patients had Fragile X-syndrome, 2 male patients with Prader Willi syndrome, two patients had Noonan syndrome (a boy and girl), 2 brothers had Goldberg Shprintzen syndrome. Ten patients each had Facioscapulohumeral muscular dystrophy, Virchow Seckel Syndrome, Mowat Wilson syndrome, Toriello-Carey Syndrome, Ruprecht Majewski-Bosma syndrome, congenital myotonic muscular dystrophy (Congenital dystrophia myotonica), extended Michelin tire baby, Congenital absent radii without thumb aplasia, Dandy walker syndrome and the syndrome of congenital facial palsy and unilateral anotia. In addition, six children patients had newly recognized syndromes (five boys and one girl). Many of the patients in this series were previously described or reported. Conclusion: This one-year Iraqi pioneering experience in the fields of clinical genetics and clinical dysmorphology should herald the end of the Dark Age in these fields in Iraq.

Approximately 4% of the world’s population suffers from rare diseases. A vast majority of these disorders have a genetic background. The number of genes that have been linked to human diseases is constantly growing, but there are still genetic syndromes that remain to be discovered. The diagnostic yield of genetic testing is continuously developing, and the need for testing is becoming more significant. Due to limited resources, including trained clinical geneticists, patients referred to clinical genetics units must be accurately selected. Around 30–40% of genetic disorders are associated with specific facial characteristics called dysmorphic features. As part of our research, we analyzed the performance of classifiers based on deep learning face recognition models in detecting dysmorphic features. We tested two classification problems: a multiclass problem (15 genetic disorders vs. controls) and a two-class problem (disease vs. controls). In the multiclass task, the best result reached an accuracy level of 84%. The best accuracy result in the two-class problem reached 96%. More importantly, the binary classifier detected disease features in patients with diseases that were not previously present in the training dataset. The classifier was able to generalize differences between patients and controls, and to detect abnormalities without information about the specific disorder. This indicates that a screening tool based on deep learning and facial recognition could not only detect known diseases, but also detect patients with diseases that were not previously known. In the future, this tool could help in screening patients before they are referred to the genetic unit.
