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.

A common example of pleiotropy is the human disease phenylketonuria (PKU). This disease causes mental retardation and reduced hair and skin pigmentation, and can be caused by any of a large number of mutations in the single gene on chromosome 12 that codes for the enzyme phenylalanine hydroxylase, which converts the amino acid phenylalanine to ...
[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] Such disorders include cystic fibrosis, [27] sickle cell disease, [28] phenylketonuria [29] and thalassaemia. [30]
Phenylketonuria (PKU)-like symptoms, including more pronounced developmental defects, skin irritation, and vomiting, may appear when phenylalanine levels are near 20 mg/dL (1200 mol/L). [1] Hyperphenylalaninemia is a recessive hereditary metabolic disorder that is caused by the body's failure to convert phenylalanine to tyrosine as a result of ...

Stoli. Stoli Group USA, the owner of the namesake vodka, filed for bankruptcy in December. A number of things went wrong for the unit, including a slowing demand for spirits, a major cyberattack ...
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 ...
