Molecular Study of Partial Deletions of AZFc Region of the Y Chromosome in Infertile Men
Background & Aims: The most significant cause of infertility in men is the genetic deletion in the azoospermia factor (AZF) region that is caused by the process of intra- and inter-chromosomal homologous recombination in amplicons. Homologous recombination could also result in partial deletions in AZF region. The aim of this research was to determine the association between the partial AZFc del...
متن کاملSocial Cognition in Williams Syndrome: Genotype/Phenotype Insights from Partial Deletion Patients
Identifying genotype/phenotype relations in human social cognition has been enhanced by the study of Williams syndrome (WS). Indeed, individuals with WS present with a particularly strong social drive, and researchers have sought to link deleted genes in the WS critical region (WSCR) of chromosome 7q11.23 to this unusual social profile. In this paper, we provide details of two case studies of c...
متن کاملGTF2I hemizygosity implicated in mental retardation in Williams syndrome: genotype-phenotype analysis of five families with deletions in the Williams syndrome region.
Most individuals with Williams syndrome (WS) have a 1.6 Mb deletion in chromosome 7q11.23 that encompasses the elastin (ELN) gene, while most families with autosomal dominant supravalvar aortic stenosis (SVAS) have point mutations in ELN. The overlap of the clinical phenotypes of the two conditions (cardiovascular disease and connective tissue abnormalities such as hernias) is due to the effect...
متن کاملGENES AND SCHIZOPHRENIA Molecular Mechanisms in 22q11 Deletion Syndrome
It is now well recognized that as well as having a characteristic facial dysmorphology and a range of congenital abnormalities, individuals with chromosome 22q11 deletion syndrome (22q11DS) have a greatly increased risk of developing psychosis, in particular schizophrenia. The majority of deletions span a large 3Mb region at 22q11. However, the presence of affected individuals carrying smaller ...
متن کاملO-7: Y Chromosome Microdeletions Are Not Associated with Spontaneous Recurrent Pregnancy Loss in A Sinhalese Population in Sri Lanka
Background: Many advances have been made in reproductive medicine yet the spontaneous loss of a pregnancy remains the most common complication of pregnancy. The aetiology of spontaneous recurrent pregnancy loss (RPL) is multifactorial. Y chromosome microdeletions are found in approximately 7% of men with low sperm counts and, compared to the general population, a higher frequency of spontaneous...
