Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.


WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

New Technique To 'Lift The Hood’ On Autism
A new study provides compelling evidence that exome-sequencing is an effective way to discover which of the 20,000 and more genes in the human genome are responsible for autism spectrum disorders.

WHO Child Growth Charts


First description in 1945, Adams-Oliver syndrome (AOS) remains a rare condition with some 130 cases reported in the medical literature to date. It is characterised by a combination of defects mainly in the formation of the scalp and/or the underlying cranium (skull) and abnormalities in the limbs.



Scientists at King’s College London have for the first time uncovered a gene responsible for Adams-Oliver Syndrome (AOS), a condition which can cause birth defects of the heart, limbs or blood vessels.

The study, published in the American Journal of Human Genetics today, gives valuable insight not only into this particular condition, but also the possible genetic causes of these common birth defects found in the wider population.

The team of researchers say that these findings could lead to better ways of treating children with these defects and may, in the future, help to find ways to recognise and ultimately prevent them from occurring.

AOS is a rare developmental condition that affects less than 150 families worldwide. But birth defects of the heart, limbs and blood vessels, seen in babies with the condition, are in fact relatively common in the general population – for example, nine in every 1,000 babies are born with a heart defect.

The team of researchers set out to investigate the genetic cause of AOS in order to detect clues to the role genes might play in congenital birth defects.

Using modern DNA technology to examine the patterns and variation of genes within two affected AOS families, the team detected mutations in the ARHGAP31 gene.

The ARHGAP31 gene regulates two proteins in the body with important roles in cell division, growth and movement. Mutations in the gene result in an imbalance in the regulation of these proteins, most likely leading to a disruption of the signalling proteins that are critical for normal limb formation.

Professor Richard Trembath, Head of King’s College London’s Division of Genetics and Molecular Medicine and Medicine Director of the NIHR BRC, said: ‘Birth defects of the heart, limbs and blood vessels can cause distress for children and their families, and tragically can sometimes even be fatal.

‘Through this study we have uncovered the first inherited factor associated with Adams-Oliver Syndrome, which gives us greater understanding of how associated birth defects develop. Understanding the genetic causes of rare diseases in this way not only helps us to understand the condition better, but it gives us a unique insight into the role of specific genes in human development on a broader scale.

‘Ultimately, this knowledge may lead us to develop better ways of treating children with these kind of abnormalities, and one day we may even be able to prevent them from developing in the first place.’

The study was part-funded by the British Heart Foundation, and the Wellcome Trust. Research was led by the National Institute for Health Research (NIHR) comprehensive Biomedical Research Centre (BRC) at King’s College London and Guy’s and St Thomas.’
