The STS gene is located on the X chromosome at band Xp22.3. Thus, the syndrome is an X-linked condition, and it affects males and females differently. The 23rd pair of chromosomes is typically termed the "sex chromosomes". Females have two X chromosomes and males have one X and one Y chromosome.
7q11.23 duplication syndrome (also called dup7 or 7dup or duplication of the Williams-Beuren syndrome critical region) is a rare genetic syndrome caused by micro-duplication of 1.5-1.8 mega base in section q11.23 of chromosome 7.
X-linked intellectual disability refers to medical disorders associated with X-linked recessive inheritance that result in intellectual disability. As with most X-linked disorders, males are more heavily affected than females. [1] Females with one affected X chromosome and one normal X chromosome tend to have milder symptoms.
[citation needed] An example of trisomy in humans is Down syndrome, which is a developmental disorder caused by an extra copy of chromosome 21; the disorder is therefore also called trisomy 21. [7] An example of monosomy in humans is Turner syndrome, where the individual is born with only one sex chromosome, an X. [8]
With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications.

Emanuel syndrome is an inherited chromosome abnormality. It is caused by the presence of extra genetic material from chromosome 11 and chromosome 22 in each cell. In addition to the usual 46 chromosomes, people with Emanuel syndrome have an extra (supernumerary) chromosome consisting of a piece of chromosome 11 attached to a piece of chromosome 22.
22q13 deletion syndrome, known as Phelan–McDermid syndrome (PMS), is a genetic disorder caused by deletions or rearrangements on the q terminal end (long arm) of chromosome 22. Any abnormal genetic variation in the q13 region that presents with significant manifestations ( phenotype ) typical of a terminal deletion may be diagnosed as 22q13 ...
Severe combined immunodeficiency (SCID), also known as Swiss-type agammaglobulinemia, is a rare genetic disorder characterized by the disturbed development of functional T cells and B cells caused by numerous genetic mutations that result in differing clinical presentations. [2]
