Abstract: | Vinculin is a cytoskeletal protein component of adherens type cell junctions. The gene had been mapped to 10q11.2-qter. We have used a combination of physical and genetic mapping techniques to refine this localization. Hybridization of the vinculin cDNA probe, HV1, to a human-rodent somatic hybrid panel initially suggested a position of either 10q11.2 or 10q22.1-10q23. Genetic recombination mapping in three-generation families with multiple endocrine neoplasia type 2 (MEN2) indicated a position distal to D10S22 (10q21.1) in 10q22.1-10q23. This was confirmed by hybridization of the vinculin cDNA to flow-sorted translocation derivative chromosomes containing the q21-qter portion of chromosome 10. We conclude that the vinculin locus maps in 10q22.1-q23, distal to D10S22. |
