  2. Compound heterozygosity - Wikipedia

    en.wikipedia.org/wiki/Compound_heterozygosity

    In medical genetics, compound heterozygosity is the condition of having two or more heterogeneous recessive alleles at a particular locus that can cause genetic disease in a heterozygous state; that is, an organism is a compound heterozygote when it has two recessive alleles for the same gene, but with those two alleles being different from each other (for example, both alleles might be ...

  3. Mucopolysaccharidosis - Wikipedia

    en.wikipedia.org/wiki/Mucopolysaccharidosis

    Approximately 1 in 100,000 newborns will experience severe mucopolysaccharidosis type I, while approximately 1 in 500,000 newborns will experience attenuated mucopolysaccharidosis type I. [2] Most mucopolysaccharidoses are autosomal recessive disorders, meaning that only individuals inheriting the defective gene from both parents are affected ...

    en.wikipedia.org/wiki/Human_genetics

    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.

  5. Genetic disorder - Wikipedia

    en.wikipedia.org/wiki/Genetic_disorder

    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]

  6. Biotinidase deficiency - Wikipedia

    en.wikipedia.org/wiki/Biotinidase_deficiency

    Biotinidase deficiency is inherited in an autosomal recessive pattern, which means the defective gene is located on an autosome, and two copies of the defective gene - one from each parent - must be inherited for a person to be affected by the disorder. The parents of a child with an autosomal recessive disorder are usually not affected by the ...

  7. Prevention of autosomal recessive disorders - Wikipedia

    en.wikipedia.org/wiki/Prevention_of_autosomal...

    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 .

  8. Homocystinuria - Wikipedia

    en.wikipedia.org/wiki/Homocystinuria

    Homocystinuria (HCU) [2] is an inherited disorder of the metabolism of the amino acid methionine due to a deficiency of cystathionine beta synthase or methionine synthase. [3] It is an inherited autosomal recessive trait, which means a child needs to inherit a copy of the defective gene from both parents to be affected.
