Autosomal recessive pattern, showing how two unaffected carriers can have a child with the disease. Some genetic disorders are caused by having two "bad" copies of a recessive allele. When the gene is located on an autosome (as opposed to a sex chromosome), it is possible for both men and women to be carriers .
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 .

CARASIL is an autosomal recessive disease, meaning that both parents must be a carrier for the allele in order for the disease to be passed on to the child. [11] As with other autosomal recessive diseases, the likelihood of receiving a recessive allele from both parents increases if the parents are closely related to each other (consanguineous).
[136] [137] [138] Inheritance of all forms of 21-hydroxylase CAH is autosomal recessive, [4] except some mild disease-causing variants such as p.V281L that seem to exert dominant negative effects on enzymatic activity. [2] Persons affected by any forms of the disease have two abnormal alleles, and both parents are usually heterozygotes (or ...
Weissenbacher–Zweymuller syndrome (WZS), also called Pierre-Robin syndrome with fetal chondrodysplasia, [1] is an autosomal recessive [2] congenital disorder, linked to mutations (955 gly-> glu) in the COL11A2 gene (located on chromosomal position 6p21.3), which codes for the α 2 strand of collagen type XI.
Hyperlysinemia has an autosomal recessive pattern of inheritance. Hyperlysinemia is inherited in an autosomal recessive manner. [2] This means the defective gene responsible for the disorder is located on an autosome, and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder.
Antley–Bixler syndrome is inherited in an autosomal recessive pattern, which means the defective gene is located on an autosome, and two copies of the gene (one inherited from each parent) are required to be born with the disorder. The parents of an individual with an autosomal recessive disorder both carry one copy of the defective gene but ...
