Turner's Syndrome Case Study
DIAGNOSIS AND OCCURANCE
Turner’s syndrome is a chromosomal condition which occurs in women due to an incomplete meiotic division. It results in the sex chromosome being incomplete and results in an ‘XO’ in the 23rd pair instead of the regular ‘XX’. This results in the birth of a female with Turner’s syndrome – resulting in a short stature, infertility, heart defects and learning disabilities. As Turner’s syndrome is due to an incomplete meiosis division, it is random and not hereditary. This affects 1 in 2000 baby girls.
During regular meiosis, in interphase the DNA is replicated once, the chromosomes will find their homologous pairs and complete ‘crossover’ this is the prophase. …show more content…
40% of Turner’s syndrome victims are born with a heart defect and this can be life threatening (Mayo Clinic, …show more content…
Hormones can be inserted into the victim so they can growth properly, as after 5 years old the Turner’s syndrome victim stops growing and growth hormone can be injected every night so the victim grows to five feet tall. Growth hormone is injected into the body, where the endocrine master gland, the pituitary gland, will send neuronic signals to the liver to produce more Insulin Growth Factor (IGF) which boost anabolic properties in order to simulate body growth (National Human Genome Reseach Institute, 2011).
As for fertility, In-Vitro Fertilisation can be used to allow the victim to have children. In-Vitro Fertilisation (IVF) is where an egg is manually fertilised outside of the body. So, in the case of Turner’s syndrome a donated egg, is manually fertilised with the father’s sperm in a laboratory, where is will grow for a few days and then be placed into the woman’s uterus (IVF Australia, 2017). IVF has up to a 45% success rate for women under 30 years old (Figure
