We have created a human chromosomal map of the location known and candidate genes involved in primary lymphedema (PLE). This should facilitate further discovery provide basis for understanding microdeletions which cause lymphedema.

Objective: Advances in the science of genetics and development assisted reproductive techniques focus on genetic causes infertility. The aim this research is to reveal abnormalities terms sex chromosome aneuploidy Y microdeletions. Material Methods: A total 350 patients with azoospermia or severe oligozoospermia were selected. After general examination laboratory investigations performed, carto...

Most microdeletion syndromes identified before the implementation of array-comparative genomic hybridization (array-CGH) were presumed to be well-defined clinical entities. However, the introduction of whole-genome screening led not only to the description of new syndromes but also to the recognition of a broader spectrum of features for well-known syndromes. Here, we report on 10 patients pres...

The natural transmission of microdeletions of the Y chromosome is occasionally reported in the literature. Here we describe the natural transmission of a partial AZFb deletion over three generations. PCR amplification of several sequence tagged site markers in the three AZF regions of the Y chromosome was carried out in a patient with oligoasthenoteratozoospermia, his father and his naturally c...

Pregnancy achieved with sperm from a patient with globozoospermia is rare, even after ICSI, since the activation of the oocyte may not occur in this disorder. Therefore, activation of the oocytes by piezoelectricity or calcium ionophores has been suggested, although spontaneous activation of the oocyte after ICSI has been reported in some cases. We report a successful pregnancy in a couple in w...

Background: Microdeletions of the long arm of the chromosome Y are the most common molecular genetic cause of severe infertility in men which affect three regions of AZFa, AZFb and AZFc (Azoospermia factor). These regions contain various genes involved in spermatogenesis. The effect of ethnicity on the patterns of Y chromosome microdeletions has not been extensively studied, particulary in Iran...

AIM To develop a high-throughput multiplex, fast and simple assay to scan azoospermia factor (AZF) region microdeletions on the Y chromosome and establish the prevalence of Y chromosomal microdeletions in Chinese infertile males with azoospermia or oligozoospermia. METHODS In total, 178 infertile patients with azoospermia (non-obstructed), 134 infertile patients with oligozoospermia as well a...

BACKGROUND Most cases of Sotos syndrome are caused by intragenic NSD1 mutations or 5q35 microdeletions. It is uncertain whether allelic or genetic heterogeneity underlies the residual cases and it has been proposed that other mechanisms, such as 11p15 defects, might be responsible for Sotos cases without NSD1 mutations or 5q35 microdeletions. OBJECTIVE To develop a multiplex ligation dependen...
