This specially-designed, practical, easy-to-use handbook presents reference data for health professionals, especially clinical geneticists, evaluating children and adults with abnormal features or syndromes. Using a mixture of graphs, tables, and charts, it presents information clinicians require to define 'normal' patterns of growth for various parts of the body, and provides the standards against which to compare possible congenital abnormalities. Numerous illustrations help to explain exactly how standardized measurements should be taken to ensure accurate and comparable documentation of growth patterns.
