X-linked mental retardation: evidence for a recent mutation in a five-generation family (MRX65) linked to the pericentromeric region.

Abstract

We report linkage analysis in a new family with nonspecific X-linked mental retardation, using 27 polymorphic markers covering the entire X-chromosome. We could assign the underlying disease gene, denoted MRX65, to the pericentromeric region, with flanking markers DXS573 in Xp11.3 and DXS990 in Xq21.33. A maximum LOD score of 3.64 was found at markers ALAS2… (More)
