ABSTRACT
Obesity has reached epidemic proportions in our patients who are of childbearing age, with pregnant patients of normal weight being in the minority. The pregnancy-related complications attributable to obesity affect not only the pregnant women, but also her fetus and potentially both mother and child for their lifetimes. Pregnancy is associated with altered immunity. The physiologic state of chronic inflammation in obesity affects systemic immunity and metabolism, and may be associated with several of the complications associated with maternal obesity. The interplay between pregnancy, obesity and inflammation may have far-reaching implications for fertility, pregnancy, the fetus and neonate.

A YAC/STS map has been assembled spanning 22 Mb across Xq12-q21.31, between markers DXS1125 and DXS95. In addition to the landmark loci for the X-inactivation center XIST and the ATRX, ATP7A, phosphoglycerate kinase, POU3F4, and choroideremia genes, the candidate disease gene regions for torsion dystonia 3 and two X-linked mental retardation syndromes are included. Also, the human voltage-dependent anion channel gene (HVDAC1) has been placed near DXS986. The current map incorporates 211 YACs from five different libraries, formatted with 185 STSs that comprise 26 genetic linkage markers, 60 newly-developed YAC-end STSs, and eight ESTs. The multiple clone coverage and average resolution of one STS per 120 kb provide resources for disease gene searches and are facilitating complete sequencing of the region.

A YAC/STS map of the X chromosome has reached an inter-STS resolution of 75 kb. The map density is sufficient to provide YACs or other large-insert clones that are cross-validated as sequencing substrates across the chromosome. Marker density also permits estimates of regional gene content and a detailed comparison of genetic and physical map distances. Five regions are detected with relatively high G + C, correlated with gene richness; and a 17-Mb region with very low recombination is revealed between the Xq13.3 [XIST] and Xq21.3 XY homology loci.
