The most common condition associated with a deletion of the end of chromosome 5 is: cri-du-chat syndrome.
Additional chromosome
Here are two examples that result in 'early fetal death' - Trisomy 13 and Trisomy 18. Meaning that when the normal [genetic] chromosomal complement is a chromosome pair, three copies of each chromosome are present and this is lethal.
PKU is described as an inherited, autosomal recessive disorder.
Women can carry or have a sex linked (x-linked) genetic disorder. Males cannot be carriers, they either have the disorder or they don't: this is because the male has only one X chromosome.
Each of the two chromatids normally contains the same genetic information.
Monosomy 21 refers to a genetic condition where an individual is missing one copy of chromosome 21, resulting in a total of only one chromosome instead of the normal pair. This condition is extremely rare and is often associated with severe developmental and physical challenges. Unlike Down syndrome, which is caused by an extra copy of chromosome 21 (trisomy 21), monosomy 21 typically leads to more severe clinical outcomes and is usually not compatible with life.
A human with monosomy has 45 chromosomes instead of the usual 46. This genetic condition results from the loss of one chromosome in a pair, leading to various health issues depending on which chromosome is affected.
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
Additional chromosome
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.
The l virus that usually causes mononucleosis is the "Epstein-Barr virus". However it can also be caused by "Cytomegalovirus".
Monosomy occurs when one chromosome is absent from the normal diploid number. This is referred to as aneuploidy which is the loss or gain of a chromosome during meiosis.An example of monosomy is Turner Syndrome. One of the sex chromosomes is missing. In an unaffected female there are 2 'X' chromosomes. But in Turner Syndrome there is one sex chromosome missing.Trisomy occurs when there is three copies of a chromosome instead of the normal diploid number. This is also referred to as aneuploidy because there was an extra chromosome added hence, an abnormal amount of chromosomes.An example of trisomy is in Trisomy 21(Downs Syndrome) in which chromosome 21 has an extra chromosome.
Sounds like the disorder is genetic and located in his x-chromosome.

Deletion Syndrome or Williams Syndrome
Genetic defects can be associated with autosome and chromosome abnormalities.
Trisomy zygotes typically have an extra chromosome, providing an extra copy of genetic material which can compensate for any missing genes and help maintain normal cellular function. Monosomy individuals, on the other hand, lack one chromosome which can lead to more severe genetic abnormalities and developmental issues, making survival less likely.
