Updated data including birth year 2020 - last update: 03/06/2022
The interactive EUROCAT prevalence charts and tables show the prevalence of 105 congenital anomaly (sub)groups. EUROCAT subgroups pool congenital anomalies together based on shared clinical characteristics and etiology. Only cases with major congenital anomalies, defined as structural changes that have significant medical, social or cosmetic consequences for the affected individual, are included in the subgroups (Chapter 3.3). Cases with only minor anomalies are excluded (3.2).
Recently, the EUROCAT subgroups of congenital anomalies were updated, based on advances in genetic diagnostic techniques, review of the literatures, data extractions from the JRC-EUROCAT Central Database and expertise from the EUROCAT Coding and Classification Committee.
The new classification (Chapter 3.3) is in use for the prevalence tables since June 2022 and applies to all cases present in the JRC-EUROCAT Central Database.
The results of the last reported year may be low, because late notifications are inevitable in the registration process.
To help interpret the data, please refer to the registries’ descriptions.
