Engreitz et al . found that mouse lncRNA inactive specific transcript (XIST) inactivating X-chromosome
was transferred from its transcription site to distant region on the X-chromosome

The occasional occurrence of scallops otherwise known to be true hermaphrodites with an abnormal sex gonad development as those with only a male gonad can be explained by the possible very low frequency occurrence of nondisjunction of the two X-chromosomes
expected in hermaphrodites, resulting in scallops inheriting only one X-chromosome
Differences in X-chromosome
transcriptional activity and cholesterol metabolism between placentae from swine breeds from Asian and Western origins.
Drumsticks are present in peripheral blood of individuals carrying more than one X-chromosome
in at least part of their granulocytes.
Many features of X-chromosome
structural abnormalities such as short stature arise from haploinsufficiency in the short stature homeobox-containing gene (SHOX), (3,4,7) whereas candidate genes for the control of normal ovarian function are postulated to be on Xp.
Additionally, X- and Y-chromosome hybridization allowed the classification of the embryos as either male (hybridization of Y-chromosome probes) or female (no hybridization of Y-chromosome probes, coupled with higher hybridization of X-chromosome
PLP is located on the long arm of the X-chromosome

These inherited conditions are carried on the X-chromosome
, so only appear in males because there is not a second X-chromosome

revealed myelolipomas and displayed X-chromosome
inactivation in both fat and haematopoietic elements, which suggests clonal origin of myelolipoma.
The best example is Rett syndrome which was diagnosed as a pervasive developmental disorder in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV)  but re-classified as a neurological disorder in the more recent fifth edition of the diagnostic manual (DSM-5)  because research found it was caused by a single X-chromosome
mutation in the methyl-CpG-binding protein 2 (MEC([p.sub.2]).
A striking example of such developmentally regulated gene control is X-chromosome
inactivation (XCI), whereby one of the two X chromosomes in females is silenced during embryogenesis.
