Which pair of genetic syndromes is known to show better verbal abilities than nonverbal abilities?

A pattern where verbal abilities outpace nonverbal (visuospatial) abilities is seen in several genetic syndromes, and these profiles are often used to differentiate them. Williams syndrome is a classic example: individuals typically have relatively strong language, vocabulary, and expressive speech for their overall cognitive level, while their visuospatial construction skills are markedly weaker. The same dissociation is commonly observed in 22q11.2 deletion syndrome, where verbal performance can exceed nonverbal performance, yielding a higher verbal IQ compared with performance IQ. Together, these two syndromes consistently exhibit better verbal than nonverbal abilities, matching the description in the question. In contrast, Fragile X usually involves more pervasive language and cognitive challenges, and Klinefelter syndrome and NF1 do not show this reliable verbal-over-nonverbal pattern.
