Examples of such accidents are development of an extra chromosome 18 (trisomy 18) and Down syndrome.
What else can I help you with?
How do chromosome mutations affect an individual?
Chromosome mutations can result in changes in the number of chromosomes in a cell or changes in the structure of a chromosome. Unlike a gene mutation which alters a single gene or larger segment of DNA on a chromosome, chromosome mutations change and impact the entire chromosome.
Which genetic disorder does an extra chromosome cause?
An extra chromosome can cause genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21. This leads to developmental delays, intellectual disabilities, and certain physical characteristics.
What are the differences between translocation and inversion mutations?
Translocation is when nonhomologous chromosomes exchange segments, like when chromosome 1 exchanges parts with chromosome 5. Inversion is when broken segments of the chromosome is inserted backwards.
What maternal conditions that interrupt oxygen flow can cause mental retardation in the fetus?
Maternal conditions like placental insufficiency, chronic hypertension, and gestational diabetes can interrupt oxygen flow to the fetus, potentially leading to mental retardation. These conditions can reduce the amount of oxygen reaching the fetus, affecting its brain development and cognitive function. Proper management and monitoring of these conditions during pregnancy are essential to minimize the risk of mental retardation in the fetus.
Is Parkinson disease on chromosome 6?
No, Parkinson's disease is not caused by a mutation on chromosome 6. The exact cause of Parkinson's disease is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Some rare forms of Parkinson's disease are linked to specific gene mutations, but these are not located on chromosome 6.
What gene is responsible for the majority of inherited mental retardation?
Fragile X, a defect in the chromosome that determines sex, is the most common inherited cause of mental retardation.
Exposure to what element can cause mental retardation?
Exposure to lead can also cause mental retardation.
Does over-study causes mental retardation?
Overstudy does not cause mental retardation.
In how many cases of mental retardation does the cause remain a mystery?
In about 35% of cases, the cause of mental retardation cannot be found.
How often does autism result in mental retardation?
The two conditions are not at all related. Autism does not cause mental retardation.
What Immunizations can prevent diseases that cause mental retardation?
Hyperthyroidism, whooping cough, chickenpox, measles, and Hib disease (a bacterial infection) may cause mental retardation if they are not treated adequately.
What maternal illnesses can cause mental retardation in infants?
Maternal infections and such illnesses as glandular disorders, rubella, toxoplasmosis, and cytomegalovirus (CMV) infection may cause mental retardation
Can being involved in an accident cause mental retardation?
In 4% of bacterial meningitis cases in children, there is seen to be some mental retardation.
What gene abnormality may cause mental retardation?
Mental retardation may be caused by an inherited abnormality of the genes, such as fragile X syndrome.
What inflammations and infections of the brain can cause mental retardation?
An infection of the membrane covering the brain (meningitis) or an inflammation of the brain itself (encephalitis) cause swelling that in turn may cause brain damage and mental retardation.
Is albinism a chromosome disorder?
no albinism is a genetic disorders that changes an offsprings physical appearance from its original parents. it may also bring out the offsprings recessive traits. its also a cause of mental retardation
What specialists may be called on to treat a child with mental retardation?
The treatment team will depend on the underlying cause of mental retardation. A neurologist, neuropsychologist, child psychiatrist, and/or development pediatrician may be helpful for nearly all cases of mental retardation
