Responding to the changing burden of disease for children and adolescents in modern Britain: the RCPCH State of Child Health Report 2017

The Royal College of Paediatrics and Child Health published the State of Child Health (SOCH) 2017, summarising the changing burden of disease in UK children and young people (CYP) over the past 20 years. These data show clearly that the three great challenges of our time for CYP are obesity, mental health problems and the impact of poverty and inequality on health. In this review, we summarise key findings from SOCH 2017 and outline key responses the UK must make to improve health and well-being for its CYP

Refined genotype-phenotype correlations in cases of chromosome 6p deletion syndromes.

Clinical reports of cases with deletions in chromosome 6p are relatively rare. We present a detailed study by fluorescent in situ hybridisation (FISH) of six new cases with distinct but overlapping 6p deletions involving the 6p24-pter chromosomal segment. Chromosomal breakpoints in individual cases were investigated using a large panel of probes previously mapped and characterised in our laboratory to cover the distal region of 6p. These cases have allowed refinement of genotype-phenotype correlations and strongly suggest a gene involved in regulating the development of hearing is localised within 6p25. There is also evidence for one or more loci involved in heart, skeletal and craniofacial development in the 6p24-p25 region. Furthermore, the Dandy-Walker malformation is associated with deletion of 6p24-pter

The ZIC gene family encodes multi-functional proteins essential for patterning and morphogenesis.

The zinc finger of the cerebellum gene (ZIC) discovered in Drosophila melanogaster (odd-paired) has five homologs in Xenopus, chicken, mice, and humans, and seven in zebrafish. This pattern of gene copy expansion is accompanied by a divergence in gene and protein structure, suggesting that Zic family members share some, but not all, functions. ZIC genes are implicated in neuroectodermal development and neural crest cell induction. All share conserved regions encoding zinc finger domains, however their heterogeneity and specification remain unexplained. In this review, the evolution, structure, and expression patterns of the ZIC homologs are described; specific functions attributable to individual family members are supported. A review of data from functional studies in Xenopus and murine models suggest that ZIC genes encode multifunctional proteins operating in a context-specific manner to drive critical events during embryogenesis. The identification of ZIC mutations in congenital syndromes highlights the relevance of these genes in human development.JOURNAL ARTICLESCOPUS: re.jinfo:eu-repo/semantics/publishe

Equitable expanded carrier screening needs Indigenous clinical and population genomic data

Expanded carrier screening (ECS) for recessive monogenic diseases requires prior knowledge of genomic variation, including DNA variants that cause disease. The composition of pathogenic variants differs greatly among human populations, but historically, research about monogenic diseases has focused mainly on people with European ancestry. By comparison, less is known about pathogenic DNA variants in people from other parts of the world. Consequently, inclusion of currently underrepresented Indigenous and other minority population groups in genomic research is essential to enable equitable outcomes in ECS and other areas of genomic medicine. Here, we discuss this issue in relation to the implementation of ECS in Australia, which is currently being evaluated as part of the national Government's Genomics Health Futures Mission. We argue that significant effort is required to build an evidence base and genomic reference data so that ECS can bring significant clinical benefit for many Aboriginal and/or Torres Strait Islander Australians. These efforts are essential steps to achieving the Australian Government's objectives and its commitment “to leveraging the benefits of genomics in the health system for all Australians.†They require culturally safe, community-led research and community involvement embedded within national health and medical genomics programs to ensure that new knowledge is integrated into medicine and health services in ways that address the specific and articulated cultural and health needs of Indigenous people. Until this occurs, people who do not have European ancestry are at risk of being, in relative terms, further disadvantaged.
