title: [Cytogenetic study of a family with 15p+ chromosomal plymorphism].
abstract: This cytogenetic study deals with a family in which some members are carriers of 15p+ polymorphism variant, with an unusually elongated short arm. The chromosomal marker segregates in three generations, duplicating its length but without phenotypic manifestation in the carriers. An analysis by using banding techniques shows us the characteristics of the p+ region and its transmission within the family.
