Identification of two novel GATA6 mutations in patients with nonsyndromic conotruncal heart defects.
GATA binding protein 6 (GATA6) encodes a zinc‑finger transcription factor that is essential for normal heart development. Mutations in this gene lead to conotruncal heart defects associated with cyanotic congenital heart disease; however, it remains unclear whether the mutations in GATA6 are also responsible for the development of the nonsyndromic conotruncal heart defects. The coding region exo...
متن کاملGenome-Wide Association Study of Maternal and Inherited Loci for Conotruncal Heart Defects
Conotruncal and related heart defects (CTDs) are a group of serious and relatively common birth defects. Although both maternal and inherited genotypes are thought to play a role in the etiology of CTDs, few specific genetic risk factors have been identified. To determine whether common variants acting through the genotype of the mother (e.g. via an in utero effect) or the case are associated w...
متن کاملGene-Gene Interactions in the Folate Metabolic Pathway and the Risk of Conotruncal Heart Defects
Conotruncal and related heart defects (CTRD) are common, complex malformations. Although there are few established risk factors, there is evidence that genetic variation in the folate metabolic pathway influences CTRD risk. This study was undertaken to assess the association between inherited (i.e., case) and maternal gene-gene interactions in this pathway and the risk of CTRD. Case-parent tria...
متن کاملIdentification of candidate genes for congenital heart defects on proximal chromosome 8p
With the application of advanced molecular cytogenetic techniques, the number of patients identified as having abnormal chromosome 8p has increased progressively. Individuals with terminal 8p deletion have been extensively described in previous studies. The manifestations usually include cardiac anomalies, developmental delay/mental retardation, craniofacial abnormalities, and multiple other mi...
متن کاملPatients with abnormal sperm parameters have an increased sex chromosome aneuploidy rate in peripheral leukocytes.
BACKGROUND Patients with oligoasthenoteratozoospermia (OAT) and normal karyotypes have an increased sperm aneuploidy rate. This may be due to an altered intratesticular environment that affects the chromosomal segregation mechanism(s). Alternatively, it may be due to a generalized meiotic and mitotic abnormality. In this case, patients with abnormal spermatogenesis should also have an increased...
