Mutations
Where a gene is going to be altered or suddenly changed and for some reason, the resulting gene abnormality may be forwarded to the child. These abnormalities are mutations, and are, thank goodness, rare. Some mutations may be caused by exposure to radiation. X-rays sometimes called chemicals, but many are preoccupied spontaneous, and once the rotation has taken place it's incurable (although some of the diseases caused turn into cured). If a man or woman has a condition due to a mutation, such as congenital dwarfism (stunted growth), it usually is passed on through the sperm or even the egg cells to fewer children.
Environmental factors
Some congenital disorders may result from environmental factors, or environmental and hereditary factors linked together. Environmental factors are circumstances externally that affect the mental and physical development of the fetus or maybe the child.
Examples of these factors are:
- Geographical location. (For indicator, Scotland has a higher a part of heart disease than the remaining United Kingdom. )
- Social reasons. Poor health Care, inferior housing and diet can produce a higher risk of congenital disorders.
- Education. Poor general or health education can lead to people being unaware which causes congenital handicap, and of the advice and experts available.
- We will give you a good or a poor environment for children. A promising environment will include sound systems antenatal and Postnatal Care, healthy living conditions, clean air and its water, and opportunities to receive intellectual and emotional challenging. A poor environment can be cultivated stunted physical growth, retardation in learning and intellectual development, so emotional problems.
Disease or deficiency indoors womb
Some congenital diseases behave as contracted during the eight months of Pregnancy by a infection being passed from a mother to the baby. A typical example is all about rubella (German measles), many, if it does not result in a miscarriage for the great women, may cause deafness, cataracts or deformity in the market child. Other virus infections could even be dangerous. Diseases as the different as syphilis (an PHOTOS, now rare) and diabetes in the market pregnant woman can cause severe harm to the unborn child. A poor or damaging diet during Pregnancy can even make the fetus suffer not enough vitamins and minerals, making a deficiency disease, and some drugs during Pregnancy might have harmful effects. One of the most tragic cases occurred when pregnant women in the early 1960s were prescribed Thalidomide (a sedative), and a number of their babies were born with serious limb deformities; but some type of antibiotics, steroids and hormones are bad to the unborn kid too. Pregnant women should take only medicines which have been Carefully selected to leave out harming the fetus.
