[16] [24] Psychiatric symptoms, for example, hallucinations, paranoia and depression, have been described in some cases [16] and affect about 5–10% of young adults. [15] Patients are also often extremely stubborn and prone to anger. [20] Psychiatric and behavioural problems are the most common cause of hospitalization. [25]
DiGeorge syndrome, also known as 22q11.2 deletion syndrome, is a syndrome caused by a microdeletion on the long arm of chromosome 22. [7] While the symptoms can vary, they often include congenital heart problems, specific facial features, frequent infections, developmental disability, intellectual disability and cleft palate. [7]
An example of bangs. Bangs (North American English) or a fringe (British English) are strands or locks of hair that fall over the scalp's front hairline to cover the forehead, usually just above the eyebrows, though can range to various lengths. While most people cut their bangs straight, they may also shape them in an arc or leave them ragged.
Turner syndrome results from a single X chromosome (45,X or 45,X0). Klinefelter syndrome, the most common male chromosomal disease, otherwise known as 47,XXY, is caused by an extra X chromosome. Edwards syndrome is caused by trisomy (three copies) of chromosome 18. Down syndrome, a common chromosomal disease, is caused by trisomy of chromosome 21.
This results in the production of gametes which have either too many or too few of a particular chromosome, and is a common mechanism for trisomy or monosomy. Nondisjunction can occur in the meiosis I or meiosis II, phases of cellular reproduction, or during mitosis .
Defective embryonic formation of the heart results in multiple holes between the heart chambers. In AVSD, all four chambers are connected, but the exact characteristics of holes and malformations may vary between patients. Even within the categories of "complete" and "partial" AVSD, multiple morphologies exist, with varying clinical consequences.
[31] [32] Not all report test results as "IQ", but most now report a standard score with a mean score level of 100. When a test-taker scores higher or lower than the median score, the score is indicated as 15 standard score points higher or lower for each standard deviation difference higher or lower in the test-taker's performance on the test ...
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).
