Unlike trisomy X, approximately half of women with tetrasomy X have no or incomplete pubertal development. Although in most cases tetrasomy X is significantly more severe than trisomy X, some cases of tetrasomy X are mild, and some cases of trisomy X severe. Like trisomy X, the full phenotypic range of tetrasomy X is unknown due to underdiagnosis.
Chromosome 15 is one of the 23 pairs of chromosomes in humans.People normally have two copies of this chromosome. Chromosome 15 spans about 99.7 million base pairs (the building material of DNA) and represents between 3% and 3.5% of the total DNA in cells.
Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic disorder in which a person's cells have only one X chromosome or are partially missing an X chromosome (sex chromosome monosomy) leading to the complete or partial deletion of the pseudoautosomal regions (PAR1, PAR2) in the affected X chromosome.
Transient myeloproliferative disease develops and may be of concern in fetuses. Features in a review of 39 reported fetal cases include: reduced platelet production often accompanied by significantly reduced levels of circulating platelets; reduced red blood cell production sometimes accompanied by mild anemia; increased levels of circulating megakaryoblasts and white blood cells; grossly ...

1 in 74,000 Cat-eye syndrome (CES) or Schmid–Fraccaro syndrome is a rare condition caused by an abnormal extra chromosome , i.e. a small supernumerary marker chromosome . [ 2 ] This chromosome consists of the entire short arm and a small section of the long arm of chromosome 22 .
Full trisomy 9 is a rare and fatal chromosomal disorder caused by having three copies of chromosome number 9.It can be a viable condition if trisomy affects only part of the cells of the body or in cases of partial trisomy (trisomy 9p) in which cells have a normal set of two entire chromosomes 9 plus part of a third copy, usually of the short arm of the chromosome (arm p).
