Biological traits are transmitted from one generation to the next through genes. Problems occur when diseases are passed to the next generation. Common genetic diseases include cystic fibrosis and sickle-cell anemia.
a condition which is the result of alterations in the genetic make-up of an individual. They may be the direct consequences of defects in single genes (mutations); or in whole chromosomes, parts of which may be lost, duplicated or misplaced; or from the interaction of multiple genes and external factors.
A disease or condition caused by an abnormality in a person's genetic blueprint. Such conditions include chromosomal disorders involving too much or too little chromosomal material, mutations of genes on the chromosomes, and mutations in conjunction with environmental factors such as exposure to drugs or radiation.
a disease or disorder that is inherited genetically
a disease caused in whole or in part by an unusual form or "mutation" of a gene
a disease or defect that is inherited and may not always be noticeable at birth
an illness that is inherited or runs in families
a problem with the baby's chromosomes or genes
a situation where some genes are missing or faulty
A hereditary condition that results from a defective gene or chromosome.
any disorder caused, wholly or in part, by a fault or faults in the inherited genetic material within a person's cells that is, in the genes formed from the DNA which make up the chromosomes in a persons cells. A large number of diseases have wholly or in part, a genetic cause. Many genetic disorders are apparent a birth and are thus also congenital.
A genetic disorder is a disease or condition caused by a variation in a person’s genetic makeup.
A disorder caused partly or completely by a defect in genes, which carry hereditary information.
A disorder caused by a faulty gene.
A disorder passed down in genes through generations of a family.
A disease or condition which originates in the genes.
a condition or mutation that results from one or more defective genes.
caused by damage to the genes (or DNA)
any disease that is caused by a mutation in a gene. These diseases are usually heritable, passed from parent to child, although mutations can occur sporadically and begin in a new generation.
A disease or condition caused by abnormal genes.
A genetic disorder is a medical condition caused by permanent changes, or mutations, in the DNA sequence of a gene or a number of genes or chromosomes.
A genetic disorder, or genetic disease, is a condition caused by abnormal expression of one or more genes resulting in a clinical phenotype. Some disorders may confer an advantage, at least in certain environments. There are a number of pathways to genetic defects, the simplest of which are summarized below.
