Linkage data for familial incontinentia pigmenti (IP2) and nine X chromosomal markers are reported. Previously found linkage between IP2 and the DXS52 locus is confirmed with the maximum lod score of 6.19 at a recombination fraction of 0.03. Linkage is also established with loci DXS134, DXS15 and DXS33. Multipoint analysis allows us to localize the IP2… (More)
A linkage study of eight families with incontinentia pigmenti (IP) has been performed, and linkage to site DXS52 has been established. We suggest that the IP locus lies in the Xq terminal region on the long arm of the X chromosome.
A linkage study of six families with spondyloepiphyseal dysplasia tarda (SEDL) has been performed. A linkage to site DXS41 ( $$\hat \theta $$ =0.08; ž=3.07) and DXS92 ( $$\hat \theta $$ =0.05; ž=2.95) has been established. We propose, that the SEDL locus lies on the distal part of the short arm of the X chromosome.
X-specific DNA probes were used to characterize the r(X) of a 45,X/46,X,r(X) female patient with Incontinentia pigmenti. It was found to be of maternal origin. Breakpoints were shown to be in or distal to p11.22 and between q12.2 and q13.1. When considering all known cases of Incontinentia pigmenti and X rearrangements at least four different break sites on… (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)
Ethylmalonic encephalopathy (EE) is a rare metabolic disorder caused by dysfunction of ETHE1, a mitochondrial dioxygenase involved in hydrogen sulfide (H2S) detoxification. Patients present in infancy with psychomotor retardation, chronic diarrhea, orthostatic acrocyanosis and relapsing petechiae. High levels of lactic acid, ethymalonic acid (EMA) and… (More)
The authors isolated five single-copy X-specific probes from an X-enriched library. These probes were regionally localized on the X chromosome by using somatic hybrid cell lines obtained from patients carrying different X-autosome translocations. Three clones were located between Xq23 and Xq26, the two others were mapped between Xp21 and Xp11.2. Analyses… (More)
An anonymous DNA probe PAS45 was isolated. This probe detects an RFLP with two alleles 1 and 2 at the same locus, with the different restriction enzymes (Bg1II, EcoRI, HindIII, PstI, MspI, XbaI). The observed polymorphism is explained by a chromosome rearrangement involving these enzyme cleavage sites. The frequency of alleles 1 and 2 was 0.875 and 0.125,… (More)
