Analysis of partial AZFc deletions in Malaysian infertile male subjects.
Complete deletions in the AZF (a, b, and c) sub-regions of the Y-chromosome have been shown to contribute to unexplained male infertility. However, the role of partial AZFc deletions in male infertility remains to be verified. Three types of partial AZFc deletions have been identified. They are gr/gr, b1/b3, and b2/b3 deletions. A recent meta-analysis showed that ethnic and geographical factors...
متن کاملPartial AZFc deletions in infertile men with cryptorchidism.
BACKGROUND A specific type of partial AZFc deletion, called 'gr/gr' deletion, was recently proposed as genetic risk factor for spermatogenic impairment and testis cancer. Since both pathologies can be part of the testicular dysgenesis syndrome (TDS), we aimed to define the role of 'gr/gr' deletion in the aethiopathogenesis of another component of the TDS: cryptorchidism. METHODS A total of 14...
متن کاملMolecular 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 کاملAssociation of partial AZFc region deletions with spermatogenic impairment and male infertility.
BACKGROUND Complete deletions of the AZFc region in distal Yq are the most frequent molecular genetic cause of severe male infertility. They are caused by intrachromosomal homologous recombination between amplicons--large, nearly identical repeats--and are found in 5-10% of cases of azoospermia and severe oligozoospermia. Homologous recombination may also generate different partial deletions of...
متن کاملDetection of Partial Deletions of Y-chromosome AZFc in Infertile Men Using the Multiplex Ligation-dependent Probe Amplification Assay
BACKGROUND In recent studies, partial deletions of the azoospermia factor c region (AZFc) on the Y-chromosome have been detected in males with infertility problems. However, there has been a lot of debate about their significance. In order to study such deletions, a simple but accurate method for their detection was applied in this study. METHODS We present data obtained from the Multiplex Li...
