In a male patient with a 45,X karyotype, the terminal part of the Y chromosome short arm was translocated as a single block on to the X chromosome. This rearranged X chromosome was, in every regard, the same as that present in XX males resulting from an abnormal X-Y interchange. Correlations between the phenotype of this patient and the extent of the deletions on the X and Y chromosomes allowed us to map the genes responsible for most features of the Turner syndrome between DXS432 and Xqter on the X chromosome, and the homologous Y genes either on Yp in interval 4 or on Yq. The molecular analysis of this X-Y translocation allowed us also to reduce the interval for the X-linked recessive chondrodysplasia punctata gene to a 1.5 Mb interval between DXS432 and DXS31.

D002806 Chondrodysplasia Punctata A heterogeneous group of bone dysplasias, the common character of which is stippling of the epiphyses in infancy. The group includes a severe autosomal recessive form (CHONDRODYSPLASIA PUNCTATA, RHIZOMELIC), an autosomal dominant form (Conradi-Hunermann syndrome), and a milder X-linked form. Metabolic defects associated with impaired peroxisomes are present only in the rhizomelic form.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
