complex inherited diseases affected by an interaction between collective effects of the genotype at one or multiple loci either to increase or to lower susceptibility to disease, combined with a variety of environmental exposures that may trigger, accelerate, exacerbate, or protect against the disease process. the new aspects of genetic techniques have been opened for diagnosis and analysis of ...

in order to study on the effect of incomplete sire's pedigree on the prediction of breeding value and estimation of genetic trend, two quantitative traits such as weaning weight and average daily gain with heritabilities 0.15 and 0.30 were simulated. phenotypic, genetic and environmental correlations were assumed 0.5. resulted data files with different proportion of missed sire pedigree (0...

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 ...

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...

At the Wageningen Laboratory of Plant Breeding, a software package has been developed to query a simple structured database with variety pedigree data. The package, called Peditree, creates a tree-shaped representation of pedigree information and has several visualization and lookup options. Estimates of inbreeding coefficient within a pedigree or coefficients of coancestry among pedigrees can ...

Motivation The collection, management and visualization of clinical pedigree (family history) data is a core activity in clinical genetics centres. However, clinical pedigree datasets can be difficult to manage, as they are time consuming to capture, and can be difficult to build, manipulate and visualize graphically. Several standalone graphical pedigree editors and drawing applications exist ...
