A series of thirteen different DNA markers was mapped relative to papillary renal cell carcinoma- and synovial sarcoma-associated translocation breakpoints in Xp11.2 using a panel of tumor-derived somatic cell hybrids in conjunction with Southern blot analysis. Our results indicate that the two translocation breakpoints differ from each other and that the(More)
Magnesium-dependent hypocalcaemia (HSH), a rare inherited disease, is caused by selective disorders of magnesium absorption. Both X-linked and autosomal recessive modes of inheritance have been reported for HSH; this suggests a genetically heterogeneous condition. A balanced de novo t(X;9)(p22;q12) translocation has been reported in a female manifesting(More)
Deficiency of coagulation factors VII and X was found in two patients (Erlangen and Nancy) who shared the same chromosomal aberration 46,XY,t(13;Y)(q11;q34) with probable loss of a terminal segment of 13q. Loci involved in synthesis or constitution of these factors may be located at 13 (q34).
A three generation family with Stickler syndrome is reported. Affected patients exhibited myopia with frequent retinal detachment or glaucoma. Most of them had characteristic facial dysmorphism, the Pierre-Robin sequence being observed in four individuals. Neonatal radiological signs of the Weissenbacher-Zweymüller syndrome were also noticed but early(More)
The enzymatic activity of phosphoribosylglycinamide synthetase (GARS) has been studied in several cases of partial monosomies and full and partial trisomies 21. An excess of GARS activity was found in regular trisomy 21 with a trisomy 21/normal ratio equal to 1.55. A 0.99 ratio was found in 21q21→21pter monosomy; a 0.54 ratio was found in 21qter→21q22(More)
Three families with anhidrotic ectodermal dysplasia (AED) have been studied by linkage analysis with seven polymorphic DNA markers from the Xp11-q21 region. Previously reported linkage to DXYS1 (Xq13-q21) has been confirmed (z(θ)=4.08 at θ=0.05) and we have also established linkage to another polymorphic locus, DXS159, located in Xq11-q12 (z(θ)=4.28 at(More)
Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant malformation of the eyelids that may severely impair visual function. Chromosomal aberrations involving chromosomes 3q23, 3p25 and 7p34 have been reported in BPES but the disease gene has not been hitherto localized by linkage analysis. We have mapped a gene for BPES to(More)
A 45,X complement was found in lymphocyte and fibroblast cultures of a male infant with severe growth and mental retardation and mild dysmorphism. Lymphocyte DNA from this patient was found to contain Yp chromosome sequences. In situ hybridization (ISH) with the 50f2 probe led to a clear assignment of euchromatic material on the short arm of chromosome 1.(More)
Linkage studies have been performed in 5 incontinentia pigmenti (IP) families totaling 29 potentially informative meioses. Ten probes of the Xp arm were used, six of them were precisely localized on the X chromosome, using hamster x human somatic cell hybrids containing a broken X chromosome derived from an incontinentia pigmenti patient carrying an X;9(More)
