title: Subregional assignment of the linked marker G8 (D4S10) for Huntington disease to chromosome 4p16.1-16.3.
abstract: The linked DNA marker for Huntington disease has recently been mapped to the short arm of chromosome 4 by somatic cell hybridization studies. Southern blot analysis of DNA from patients with Wolf-Hirschhorn syndrome (WHS) has suggested that the linked marker maps within the terminal 4p16 band. We have now accomplished subregional assignment of G8 (D4S10) to 4p16.1-16.3 using in situ hybridization techniques on two patients with nonoverlapping interstitial deletions of 4p. The mapping of G8 (D4S10) to a region deleted in patients with WHS will allow the application of new strategies for detecting DNA sequences closer to the locus for Huntington disease.
