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!

WHO Child Growth Charts

Autism Spectrum Disorder (ASD) affects about 1 in 100 children resulting in a range of problems in language, communication and understanding other people's emotional cues, all of which can lead to difficulties in social situations.

Boys are three to four more times as likely to be affected as girls and consequently it has been suggested that the genes involved in this disorder may be linked to the X chromosome.

New research published in BioMed Central's open access journal Molecular Autism used genome wide association study (GWAS) data to find a variation in the gene for transducin ß-like 1X-linked (TBL1X) which is associated with increased risk of ASD in boys.

A team of researchers across America combined three sets of genomic data incorporating over 3000 affected children and their family members or non-related case control individuals.

The GWAS study compared single nucleotide polymorphisms (SNP) on the X chromosomes of the children with ASD to the control groups, and found differences within the genes for Duchenne muscular dystrophy (DMD), IL1RAPL2 (involved in inflammation), and in TBL1X.

TBL1X is part of the Wnt-signaling pathway, which is in turn part of the complex mechanism controlling embryonic neurological development and the maintenance of brain function in adults.

Prof Eden Martin from the Hussman Institute for Human Genomics, who lead the multi-centre team explains:

"The SNP in TBL1X is associated with an increase in risk for ASD of about 15%. This could reflect either an unidentified rare mutation (or mutations), which has large impact, or a more common change with a more subtle effect, on the development of ASD. Further study of TBL1X will help us to pinpoint the DNA changes involved and help us to understand exactly how these changes and the Wnt-signaling pathway is involved in ASD."

Other researchers involved in the study are: Ren-Hua Chung, Deqiong Ma, Kai Wang, Dale J Hedges, James M Jaworski, John R Gilbert, Michael L Cuccaro, Harry H Wright, Ruth K Abramson, Ioanna Konidari, Patrice L Whitehead, Gerard D Schellenberg, Hakon Hakonarson, Jonathan L Haines, Margaret A Pericak-Vance and Eden R Martin
Molecular Autism (in press)

Molecular Autism is a peer-reviewed, online open access journal that publishes high-quality basic, translational and clinical research into the molecular basis of autism and related neurodevelopmental conditions.

BioMed Central (http://www.biomedcentral.com/) is an STM (Science, Technology and Medicine) publisher which has pioneered the open access publishing model.
