In humans genes that determine sex are in a pair of chromosomes (gnomosomes), the other 22 pair are called autosomes. Males have 22 pairs of autosomes and XY chromosomes, while females have 22 pairs of autosomes and XX chromosomes.
Supposing the case of a gene not determining a sex characteristic. However this gene is located on the X chromosome. The case of this chromosome it’s said to be sex linked ( this make Hemophilia and color blindness ) In this case, it can only be transmitted from father to son.
We consider a rare disease, one that have low incidance in the population, it isn´t very common.
ALD is a genetic disease due to a X-link gene manifestation. It’s due to a abnormal accumulation of fats in the central nervous system and it causes the loss of myelin surrounding the axon of important neurons. The signs and symptoms are: Ataxia, abnormal behaviour, seizures, dementia… it conclude with dead. The probability of having a child with ALD 25%.
It propagates electrical impulses along neurons.
Fatty acids: Long chains of Hydrocarbons Fatty acid chains with single bonds between the carbon atoms surrounded by hydrogen atoms are termed saturated, but if there are double bond between them, the chain is termed unsaturated.
One single bond: monounsaturated Two or more bonds: polyunsaturated Saturated fats are present in oil, meat… Monounsaturated fats are present in sunflower oil… Polyunsaturated fats are present in oily fish…
It’s an X-linked recessive disease. Itreduces bloods clot formation in trauma and heavy bleeding. Female carriers it.
