Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

ANP is synthesized as an inactive preprohormone, encoded by the human NPPA gene located on the short arm of chromosome 1. [6] The NPPA gene is expressed primarily in atrial myocytes and consists of 2 introns and three exons , with translation of this gene yielding a high molecular mass 151 amino acid polypeptide known as preproANP.

The human leukocyte antigen (HLA) system, also referred to as the major histocompatibility complex (MHC), is a complex of genes important for the adaptive immune system. Mutations in the HLA complex have been associated with an increased risk of developing hypersensitivity reactions in response to certain medications.
The chromosome is ~193 megabases in length. In a 2012 paper, 775 protein-encoding genes were identified on this chromosome. [4] 211 (27.9%) of these coding sequences did not have any experimental evidence at the protein level, in 2012. 271 appear to be membrane proteins. 54 have been classified as cancer-associated proteins.
Drug metabolism is the metabolic breakdown of drugs by living organisms, usually through specialized enzymatic systems. More generally, xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") is the set of metabolic pathways that modify the chemical structure of xenobiotics, which are compounds foreign to an organism's normal biochemistry, such as any drug ...
The variance seen in outcomes of alcohol consumption during pregnancy is poorly understood. Aggravating factors may include advanced maternal age, smoking, poor diet, [33] [34] genetics, and social risk factors. [35] The risk of FASD increases with amount consumed, the frequency of consumption, and longer duration of alcohol consumption during ...
An example plasmid with two areas of antibiotic resistance coding DNA (1,2) and an origin of replication (3).. Plasmid-mediated resistance is the transfer of antibiotic resistance genes which are carried on plasmids. [1]
The genetics and abortion issue is an extension of the abortion debate and the disability rights movement. Since the advent of forms of prenatal diagnosis , such as amniocentesis and ultrasound , it has become possible to detect the presence of congenital disorders in the fetus before birth .
