Novel Neurocognitive Profile in a Minority of Boys with 47,XXY (Klinefelter Syndrome)

Discussion: To the best of our knowledge, this is the first study to identify an alternative profile of 47,XXY with increased verbal capabilities in comparison with perceptual skills. In addition, previous research has found that boys with 47,XXY often show increased receptive vocabulary skills in comparison with their expressive vocabulary skills early in life. Therefore, our findings of commensurate expressive and receptive vocabulary skills suggest that age may be an impactful factor in vocabulary development. Further research is necessary to determine individualized treatment options for these patients, focusing on the specific cognitive profile they present.
