It should be noted, however, that due to small sample sizes and potential cryptic Y-chromosome mosaicisim of patients, there has been controversy as to whether phenotypes could be attributed specifically to parental origin of the X chromosome Furthermore, it will be important to ascertain the epigenetic mechanisms controlling X-linked imprinting.
In addition, a study has shown that hearing loss in TS was related to serum concentrations of IGF-1 and height [ ].
Sometimes, abnormalities in the structure or number of chromosomes can cause irregularities in the physical and mental development of affected individuals. Most sex chromosome disorders are not inherited. Prenatal testing can also be performed.

The authors take a thorough approach to the challenging issues to ascertainment bias in studies of SCT - adjusting their methods for power analysis and participant selection. Assessment battery. Gillberg C Chromosomal disorders and autism. An interesting finding of all these studies is that methylation-based and expression-based pathway analyses are complementary, rather than overlapping, and are correlated with the clinical picture displayed by TS subjects.
