No " following, but a condition such as trisomy 21, Downs syndrome, is caused by nondisjuction. The chromosomes fail to separate properly and one child is left with an extra chromosome number 21. The potetial other children that could have been born of this nondijuction event, those with only one chromosome 21, are not viable.
Klinefelter's syndrome is caused by the presence of an extra X chromosome in males (XXY), typically resulting in developmental and hormonal differences. Turner syndrome is caused by the complete or partial absence of one of the X chromosomes in females (X0), leading to underdeveloped ovaries and infertility. Both conditions occur due to chromosomal abnormalities during conception.
Leigh syndrome is primarily caused by genetic mutations that interfere with the functions of mitochondria, leading to impaired energy production. These mutations can be inherited or can occur spontaneously. As a result, affected individuals experience progressive neurological deterioration and other complications.
Prolonged QT syndrome is a heart condition where the electrical activity of the heart is affected, causing a delay in the repolarization of the ventricles. This delay can lead to abnormal heart rhythms (arrhythmias) that can be life-threatening, such as torsades de pointes. It can be inherited or acquired through certain medications or medical conditions.
Wallenberg syndrome is a type of brain stem stroke manifested by imbalance, vertigo, difficulty swallowing, hoarseness of voice, and sensory disturbance.
The syndrome is also known as lateral medullary infarct (LMI) or posterior inferior cerebellar artery syndrome (PICA).
There is a 10% death rate due to complications like aspiration pneumonia, breathing difficulty, and cardiac arrhythmias.
Aim of treatment is to alleviate symptoms, modify underlying risk factors, and prevent complications and future strokes.
