title: Assignment of three gene loci (PGK, HGPRT, G6PD) to the long arm of the human X chromosome by somatic cell genetics.
abstract: The intrachromosomal localization of three X-linked gene loci (PGK, HGPRT and G6PD) has been determined using a somatic cell genetic approach. A human cell line possessing an X/14 translocation was used as one parent in the formation of human/mouse hybrids. The translocation separates the human X into two parts: Xp and t(Xq14q). The data indicate that all three X-linked loci segregate with the t(Xq14q) rearrangement product thus permitting their assignment to the X chromosome's long arm. Secondary rearrangements and data from other laboratories suggest that the order of the the three markers from the centromere to the distal end of the X long arm is PGK, HGPRT, G6PD. It was also observed that NP, an autosomal locus, segregated with the t(Xq14q) chromosome. This provides strong support for the assignment of NP to 14.
