Y chromosome haplogroups may confer susceptibility to partial AZFc deletions and deletion effect on spermatogenesis impairment.
BACKGROUND Partial AZFc deletions related to testis-specific gene families are common mutations of the Y chromosome, but their contribution to spermatogenic impairment is still unresolved, and the risk factors for the formation of the deletions remain unknown. With this in mind, we investigated the possible association between Y chromosome haplogroups and predisposition to partial AZFc deletion...
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 کاملImpaired Spermatogenesis and gr/gr Deletions Related to Y Chromosome Haplogroups in Korean Men
Microdeletion of the Azoospermia Factor (AZF) regions in Y chromosome is a well-known genetic cause of male infertility resulting from spermatogenetic impairment. However, the partial deletions of AZFc region related to spermatogenetic impairment are controversial. In this study, we characterized partial deletion of AZFc region in Korean patients with spermatogenetic impairment and assessed whe...
متن کاملPartial deletions in the AZFc region of the Y chromosome occur in men with impaired as well as normal spermatogenesis.
BACKGROUND Partial deletions of the AZFc region of the Y chromosome were reported to be a significant risk factor for oligo-/azoospermia. In this study, we assessed the occurrence and frequency of partial AZFc microdeletions in patients with spermatogenic failure and in controls with normal spermatogenesis. METHODS In a retrospective study design, gr/gr, b1/b3 and b2/b3 deletions were analyse...
متن کاملAZF microdeletions and partial deletions of AZFc region on the Y chromosome in Moroccan men.
AIM To evaluate for the first time the frequency of Y chromosome microdeletions and the occurrence of the partial deletions of AZFc region in Moroccan men, and to discuss the clinical significance of AZF deletions. METHODS We screened Y chromosome microdeletions and partial deletions of the AZFc region of a consecutive group of infertile men (n = 149) and controls (100 fertile men, 76 normosp...
