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.
What inborn metabolism problem can result in mental retardation?
Single gene defects such as phenylketonuria (PKU) and other inborn errors of metabolism may also cause mental retardation if they are not found and treated early.
How do clans abnormality involve in heridity?
most of abnormality in a clans is due to the inheritance of mutated gene from parents , since in most clans individuals intermarried in the clans itself . therefore the mutated gene(responsible for the abnormality) remains in the progeny , thus clans abnormality is involved ion heredity
What chromosome mutations can cause mental retardation?
Chromosome mutations such as aneuploidy (caused by trisomy or monosomy of specific chromosomes), microdeletions (e.g. Cri du Chat syndrome), and translocations (e.g. Fragile X syndrome) are known to be associated with mental retardation or intellectual disabilities. These mutations can disrupt normal gene function and development in the brain, leading to cognitive impairments.
Diseases that result from an abnormality in or a mutation of a gene are termed what type of disease?
Genetic diseases
Is cystic fibrosis chromosomal abnormality?
Yes, it is caused by a mutation in the gene for the protein CFTR.
What can cause epidermolysis bullosa?
Epidermolysis bullosa is a genetic disorder caused by mutations in genes that help hold the layers of the skin together. These mutations result in fragile skin that is prone to blistering and tearing from minor friction or trauma.
Is diabetes congenital?
Diabetes can be congenital. It results when the child inherits a faulty gene for insulin production.
What is the desired outcome of gene therapy?
Gene therapy has the desired outcome of eradicating or curing diseases that are caused by a specific abnormality or mutation of a gene that is a killer. It is a developing science and slowly getting results.
If Rett syndrome is a chromosomal abnormality what is the abnormality?
Rett syndrome is not primarily caused by a chromosomal abnormality, but rather a genetic mutation in the MECP2 gene located on the X chromosome. This gene provides instructions for making a protein that is important for brain development. Mutations in the MECP2 gene disrupt the production of this protein, leading to the characteristic features of Rett syndrome.
What has the author Noel Gene Markwell written?
Noel Gene Markwell has written: 'The teenager's conception of mental illness' -- subject(s): Mental illness
What causes disease fragile x?
The fragile X syndrome is a genetic disorder caused by mutation of the FMR1 gene on the X chromosome.Expansion of the CGG repeating codon to such a degree results in a methylation of that portion of the DNA, effectively silencing the expression of the FMR1 protein.Mutation of the FMR1 gene leads to the transcriptional silencing of the fragile X-mental retardation protein, FMRP.
