Identification of a complex congenital heart defect susceptibility locus by using DNA pooling and shared segment analysis

Sheffield, V.·1997·Human Molecular Genetics

Abstract

The identification of genetic loci involved in most forms of congenital heart disease has been hampered by the complex inheritance patterns of these disorders. Atrioventricular canal defects (AVCDs) are most commonly associated with Down syndrome, although non-syndromic cases also occur. Non-syndromic AVCDs have been attributed to multifactorial inheritance. However, the occurrence of a few kindreds with multiple affected individuals has suggested that a major genetic locus can account for the disorder in some families. We have used a combination of DNA pooling and shared segment analysis to perform a high density screen of the entire autosomal human genome in an extended kindred. In so doing, we have identified a genetic locus on chromosome 1 shared by all affected individuals. Our data demonstrate the existence of a congenital heart defect susceptibility gene, inherited as an autosomal dominant with incomplete penetrance, involved in AVCD. Furthermore, our data demonstrate the power of using key isolated kindreds in combination with high density genomic screens to identify loci involved in complex disorders such as congenital heart defects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
