Author Description

Fully updated, including data up to September 1999, the London Dysmorphology Database (LDDB) now contains information on 3030 non-chromosomal, multiple congenital anomaly syndromes. There are also 28,323 references. LDDB arose from the need to diagnose and provide genetic counselling for the hundreds of rare syndromes which are associated with mental retardation and congenital anomalies. Work began on the database in 1981 with the intention of ascertaining the majority of reported syndromes in the literature. All the major reference works are consulted, as well as all journals that might contain a report of multiple congenital anomaly syndromes.
