congenital cutis laxa is an exceptional condition. no large scale pedigree has been reported from iran. we report a family with 106 members with two members affected with cutis laxa. our cases were two patients (male and female) with pre- and postnatal growth retardation, cutis laxa, characteristic facies and other manifestations which proved that they were affected with cutis laxa. their famil...

The Pedigree Visualizer is a system for visualization of pedigree diagrams. It accepts a simple text-based specification of a pedigree diagram. The pedigree diagram is then layout automatically. Both GIF- and PS-formatted output files are produced. In addition, the Pedigree Visualizer also provides a rich set of functions for the manipulation and management of large pedigree files.

common variable immunodeficiency (cvid) and selective iga deficiency (sigad) are the most common primary antibody deficiencies. these two diseases may have coincidence in one family and sigad can progress to cvid which suggest common underlying genetic defects between sigad and cvid. this study was designed to find the prevalence of multiple cases in families of iranian patients with cvid or si...

Interest has surged recently in removing siblings from population genetic data sets before conducting downstream analyses. However, even if the pedigree is inferred correctly, this has the potential to do more harm than good. We used computer simulations and empirical samples of coho salmon to evaluate strategies for adjusting samples to account for family structure. We compared performance in ...

MOTIVATION Haplotype reconstruction is an essential step in genetic linkage and association studies. Although many methods have been developed to estimate haplotype frequencies and reconstruct haplotypes for a sample of unrelated individuals, haplotype reconstruction in large pedigrees with a large number of genetic markers remains a challenging problem. METHODS We have developed an efficient...

Maximization of genetic gain in forest tree breeding programs is contingent on the accuracy of the predicted breeding values and precision of the estimated genetic parameters. We investigated the effect of the combined use of contemporary pedigree information and genomic relatedness estimates on the accuracy of predicted breeding values and precision of estimated genetic parameters, as well as ...
