An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.
Modifying a person's non-heritable DNA with the goal of improving one's medical condition is generally accepted and has a plethora of ethical protocols monitoring such procedures. [19] This includes modifications like organ donation, bone marrow transplants, and types of gene therapies, all of which consider cultural and religious values. [19]
These include Huntington's disease, cystic fibrosis or Duchenne muscular dystrophy. Cystic fibrosis, for example, is caused by mutations in a single gene called CFTR and is inherited as a recessive trait. [16] Other diseases are influenced by genetics, but the genes a person gets from their parents only change their risk of getting a disease.
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens.
NMD is a cellular mechanism that degrades mRNAs containing premature termination codons (PTCs), which can arise from mutations. Comprehensive analyses large scale genetics and gene expression datasets have enabled the systemic identification of the complex rules governing NMD efficiency, and quantification of their relative importance and effect size.

The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
A genetic disorder is a health problem caused by one or more abnormalities in the genome.It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality.
Twin studies have found CU traits to be highly heritable, and not significantly related to environmental factors such as socioeconomic status, school quality, or parent quality. [6] Two twin studies suggested a significant genetic influence for CU, with an estimated average amount of variation (42.5%) in CU traits accounted for by genetic ...
