title: A heritable fragile 12q24.13 segregating in a family with the fragile X chromosome.
abstract: A fragile site on chromosome 12, at 12q24.13, was found in the lymphocytes of two members of a family during the study for detection of a fragile X chromosome. The site was found to be heritable and folate-sensitive, and it fulfills all four criteria for a fragile site. It thus can now be confirmed as the heritable fragile site FRA12C.
