Background: Klinefelter syndrome (47,XXY; KS) influences neurodevelopment, resulting in a neurocognitive profile with a more pronounced impact on verbal IQ compared to performance IQ. Additionally, KS is linked to changes in the epigenome and transcriptome. The relation between these epigenetic and genetic changes and the neurocognitive phenotype has yet to be determined.Methods: We conducted a comprehensive and integrat...

Background: Turner syndrome (TS) is associated with short stature, hypogonadism, autoimmune diseases and metabolic conditions. Genome-wide changes in TS affect both transcriptome and methylome. Genomic studies have primarily focused on 45,X, but only 35-45% of the TS population has 45,X, while the remaining TS have other karyotypes.Methods: We used 5 study cohorts. A “genomic cohort” of TS with 45,X karyotype...
