Certain other phenotypes, such as wet versus dry earwax, are also determined in an autosomal recessive fashion. [24] [25] Some autosomal recessive disorders are common because, in the past, carrying one of the faulty genes led to a slight protection against an infectious disease or toxin such as tuberculosis or malaria. [26]
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.
Autosomal recessive inheritance, a 25% chance, and (purple) a 50% carrier chance. Autosomal recessive traits is one pattern of inheritance for a trait, disease, or disorder to be passed on through families. For a recessive trait or disease to be displayed two copies of the trait or disorder needs to be presented.
Autosomal genetic disorders which exhibit Mendelian inheritance can be inherited either in an autosomal dominant or recessive fashion. [7] These disorders manifest in and are passed on by either sex with equal frequency. [7] [8] Autosomal dominant disorders are often present in both parent and child, as the child needs to inherit only one copy ...
Phenylketonuria is inherited in an autosomal recessive fashion PKU is an autosomal recessive metabolic genetic disorder . As an autosomal recessive disorder, two PKU alleles are required for an individual to experience symptoms of the disease.
Bloom syndrome is an autosomal recessive disorder, caused by mutations in the maternally- and paternally-derived copies of the gene BLM. [13] As in other autosomal recessive conditions, the parents of an individual with Bloom syndrome do not necessarily exhibit any features of the syndrome.
During that time, Agatson and Gartner suggested a possible link between Werner's syndrome and cancer. However, it was not until 1966 that there was a general consensus on the autosomal recessive mode of inheritance for the syndrome. By 1981, geneticists had located the WRN gene on chromosome 8, leading to its cloning in 1996.
