PHENOTIP - A novel web-based tool for improving prenatal diagnostic accuracy of syndromes. About 6,000 dysmorphic syndromes are known to science. The accurate prenatal diagnosis of a syndrome cannot be overemphasized, as it holds great importance both for the family and the caring physician. The midtrimester ultrasound scan is the primary test to discover anatomical abnormalities in the developing fetus. Enhanced ultrasound resolution and improved technology allow the in utero diagnosis of even subtle findings. Many, if not all syndromes manifest as developmental abnormalities in one or more organs. Currently, there is no free tool that can offer a differential diagnosis based on the sonographic findings in the anatomy scan. The lack of a useful tool brought us to design Phenotip - a FREE web-based database of sonographic markers of syndromes. All data in the database is based on previously published data of prenatal sonographic findings. The search in the database is user-friendly and very intuitive. We pursue to deepen and broaden our database, incorporate more syndromes, add more data and improve the search algorythm. ALL AS PRO-BONO PROJECT SOLELY FOR THE BENEFIT OF THE PATIENTS.
