Is 5p syndrome caused by a chromosomal abnormality?
Yes, 5p syndrome, also known as Cri du Chat syndrome, is caused by a chromosomal abnormality involving a deletion of a portion of the short arm of chromosome 5. This genetic alteration leads to a range of developmental and physical challenges, including distinctive cat-like cry in infants, intellectual disability, and various physical abnormalities. The severity of symptoms can vary widely depending on the size and location of the deletion.
What is the karyotype of klienfeter syndrome?
Individuals with Klinefelter syndrome typically have an extra X chromosome, resulting in a karyotype of 47,XXY. This chromosomal abnormality can cause developmental and reproductive issues in affected individuals.
What maternal age is associated with increased risk of conceiving a child with a chromosomal abnormality?
Maternal age is associated with an increased risk of conceiving a child with a chromosomal abnormality, particularly after the age of 35. As women age, the quality of their eggs declines, which can lead to higher rates of conditions like Down syndrome and other chromosomal disorders. The risk continues to rise significantly with age, especially for women over 40.

Is Rett syndrome a nondisjunction disorder?
No, Rett syndrome is not a nondisjunction disorder. It is primarily caused by mutations in the MECP2 gene, located on the X chromosome, and is typically inherited in an X-linked dominant manner. Nondisjunction disorders, such as Down syndrome, result from errors in chromosome separation during cell division. In contrast, Rett syndrome arises from specific genetic mutations rather than chromosomal abnormalities.
What chromosomal abnormality causes Turner syndrome?
