title: Nucleolus organizer regions (NORs) inserted in 6q15.
abstract: We studied a family in which three of the members present one chromosome 6 with an isochromatid gap at the band 6q15 level. Studies of the chromosomes by various banding techniques suggested that the secondary constriction represents a stalk from an acrocentric chromosome inserted into 6q15. The possible influence of the abnormal localization is considered.
