摘要：

Linkage analysis was performed in six families segregating for X-linked ocular albinism of the Nettleship-Falls type using four polymorphic DNA markers from the distal Xp. Linkage was found between the disease locus (OA1) and the loci DXS237 (θmax = 0.06, zmax = 2.82), DXS278(θmax = 0.03, zmax = 5.27) and DXS16 (θmax = 0.10, zmax = 2.33). The analysis of multiple informative meioses suggests that OA1 maps between DXS278/DXS237 and DXS143/DXS16. Multipoint linkage analysis slightly favours the order DXS278/DXS237-OA1-DXS16. These data refine the genetic localization of OA1 and may be useful for carrier detection in X-linked ocular albinism by DNA analysis. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
