Global developmental delay with speech and behavioral abnormalities

Summary

Global developmental delay with speech and behavioral abnormalities (GDSBA) is characterized by developmental delay apparent from infancy or early childhood. Affected individuals have mildly delayed fine and motor skills with walking by 3 years of age, mildly impaired intellectual development, speech and language delay, and variable behavioral abnormalities, mostly autism and ADHD. Some patients may have additional nonspecific features, such as facial dysmorphism, myopia or strabismus, and skeletal defects, including joint hypermobility, pes planus, or slender fingers (summary by Granadillo et al., 2020).
