Role of mutator alleles in adaptive evolution

Mutator genotypes generate adaptive mutations efficiently. Therefore we suggest that a transient increase in mutator frequencies should be a common event in natur ...

Saethre–Chotzen syndrome
Saethre–Chotzen syndrome (SCS), also known as Acrocephalosyndactyly type III is a rare congenital disorder associated with craniosynostosis (premature closure of one or more of the sutures between the bones of the skull). This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids (ptosis), widely spaced eyes (hypertelorism), and minor birth defects of the hands and feet (syndactyly). In addition, individuals with more severe cases of SCS may have mild to moderate mental retardation or learning disabilities. Depending on the level of severity, some individuals with SCS may require some form of medical or surgical intervention. Most individuals with SCS live fairly normal lives, regardless of whether medical treatment is needed or not.
