[ 1 ] - O-27: Genome Instabilities in Preimplantation Development Leading to Genetic Variation between Tissues of Normal Human Fetuses
Background: Origin of midlife copy number variations (CNVs) between tissues in non-genetic diseases is unknown. Such genomic differences caused by post-zygotic events. They might either happen during the life or due to prevalent mosaicism in preimplantation stage. We aim to explore fetal mosaicism and its origins. Materials and Methods: Two apparently normal fetuses were achieved following the ...
[ 2 ] - P-230: Analysis of TEX15 Expression in Testis Tissues of Severe Oligozoospermic and Non-Obstructive Azoospermic Men Referred to Royan Institute
Background: TEX15 is a novel protein that is required for chromosomal synapsis and meiotic recombination. Human TEX15 is located on chromosome 8(8p12 region) and expressed in testis and ovary, as is its mouse ortholog. Loss of TEX15 function in mice causes early meiotic arrest in males but not in females. Specifically, TEX15 deficient spermatocytes exhibit a failure in chromosomal synapsis. In ...
[ 3 ] - P-198: Analysis of Expression Level of TEX12 Gene in Testis Tissues of Severe Oligozoospermic and Non-Obstructive Azoospermic Men
Background: During the first meiotic prophase, alignment and synapsis of the homologous chromosomes are mediated by the synaptonemal complex. Incorrect assembly of the synaptonemal complex leads to impaired recombination and cell death, which in humans, causes infertility in males. Testis-expressed gene 12 (TEX12) is a germ cell-specific gene that is located on the chromosome 11 (11q22) in huma...
[ 4 ] - P-195: Analysis of Expression Level of Tex11 Gene in Obstructive and Non-Obstructive Azoospermic Men Referred to Royan Institute
Background: About 15% of couples worldwide suffer from infertility problem that half of these cases are related to male infertility. Spermatogenesis is a cumulative process and thousands of genes are involved in it. Change in one of these genes or their products can cause male infertility. Tex11 is a germ cell specific gene that is located on the X chromosome (Xq13.1 region). This gene was iden...
[ 5 ] - P-206: Mov10l1 Gene Polymorphisms Are Probably Associated to Male Infertility in Azoospermic Men with Complete Maturation Arrest
Background: Thousands of genes are involved in spermatogenesis. Alterations in any of these genes could lead to male infertility. Moloney leukemia virus 10-Like 1 (Mov10l1) gene is one of the genes that are expressed specifically in germ cells. Genetic disruption of this gene in mouse stops spermatogenesis during Meiosis I and causes azoospermia. Materials and Methods: In this study, the geneti...
