Connexin 26 (GJB2) gene mutations linked with autosomal recessive non-syndromic sensor neural hearing loss in the Iraqi population.

Deafness is a total or partial hearing loss that may appear at any age and with different degrees of severity. Approximately 50% of hearing loss have a genetic origin, and among them, non-syndromic sensorineural deafness represents about 70% of the cases. From them, 80% correspond to autosomal recessive inheritance deafness.

Prevalence of Y chromosome microdeletion in azoospermic infertile males of Iraqi population.

In human gamete development, the important period is spermatogenesis, which is organized by specific genes on Y chromosome. In some cases, the infertile men have shown microdeletions on Y chromosome, which seemed as if the structural chromosome variance is linked to the reduction of sperm count. This study aimed to determine the frequency and patterns of Y chromosome microdeletions in azoospermia factor (AZF) of Iraqi infertile males.

The role of Y chromosome C-band size polymorphism in male infertility with a reference to their effect on the total length of the chromosome.

Objective: To assess the contribution of chromosome on sperm production.

Methods: During a 2 year period from October 1999 to December 2001 a total of 200 male patients were included in the present study. The study was carried out at Kufa Medical College, Kufa, Iraq.

The significance of autosomal C-band size polymorphism in male infertility.

Objective: The aim of this study is to assess the possible role of autosomal C-band size polymorphism in male infertility.

Methods: Two-hundred male patients with clinical diagnosis of infertility and 100 normal controls were included in the present investigation. All patients were assessed by Urologist Consultant at the Department of Pathology and Forensic Medicine, Kufa University, Kufa, Iraq, during a 2-year-period, October 1999 to October 2001.
