A large Danish pedigree segregating for X-linked retinitis pigmentosa (RPX) (Warburg and Simonsen 1968) was restudied for linkage analysis. Using two markers, i.e. the DNA base sequence polymorphism presented by the probe L1.28 defining the chromosomal segment DXS7, and the C-banding heteromorphism

✦ Synopsis
A large kindred with the X-linked dominant form of peroneal muscular atrophy (Charcot-Marie-Tooth disease) was analyzed for individual variation in the length of DNA fragments after restriction endonuclease digestion. A systematic search was performed for linkage with a series of cloned single-copy DNA sequences of known regional assignment to the human X chromosome. Close linkage was found with the pDP34 probe (DXYS1 locus, Xql3-q21), suggesting that the gene responsible for the disease is located on the proximal long arm of the X chromosome.

Norrie disease (ND) is an X-linked recessive disorder with congenital blindness (atrophia bulborum hereditaria, pseudoglioma). Six kindreds segregating for ND were studied for linkage with polymorphic markers of the human X chromosome. No recombination was observed between the ND-locus (NDP) and the
Recently linkage has been described between the Duchenne muscular dystrophy (DMD) gene and a cloned DNA sequence, RC8, that detects restriction fragment length polymorphism and is derived from the distal short arm of the X chromosome. Positive lod scores between RC8 and Xg prompted us to examine the
