Chromosomal Abnormality in Men with Impaired Spermatogenesis

Chromosomal Abnormality in Men with Impaired Spermatogenesis

BACKGROUND Chromosomal abnormalities and Y chromosome microdeletions are regarded as two most frequent genetic causes associated with failure of spermatogenesis in the Caucasian population. MATERIALS AND METHODS To investigate the distribution of genetic defects in the Romanian population with azoospermia or severe oligozoospermia, karyotype analysis by G-banding was carried out in 850 idiopa...

Chromosomal abnormality in patients with secondary amenorrhea.

BACKGROUND Secondary amenorrhea is a condition in which there is cessation of menses after at least one menstruation. It is a symptom of different diseases, such as hormonal disturbances which range from pituitary to ovarian origin, as well as chromosomal abnormalities. Knowledge of the distinct cause of secondary amenorrhea is of tremendous benefit for the management and monitoring of patients...

Consanguinity and chromosomal abnormality

BACKGROUND: Consanguinity is defined as the marriage between close relatives. The deleterious effects associated with consanguinity may be caused by the expression of rare recessive genes inherited from common ancestors. AIMS AND OBJECTIVES: The present study was undertaken to analyze the effect of consanguinity on chromosomal abnormality (CA). METHODS AND MATERIALS: During last 6 years period,...

Heterogeneous nuclear ribonucleoprotein G-T (HNRNP G-T) mutations in men with impaired spermatogenesis.

The genetic cause of male subfertility due to impaired spermatogenesis is unknown in the majority of cases, but the general assumption is that it is a complex disorder. The aim of this study was to determine whether mutations occur in the HNRNP G-T gene in men with idiopathic impaired spermatogenesis. The heterogeneous nuclear ribonucleoprotein G-T (HNRNP G-T) gene is located in chromosomal reg...

Cytogenetic Analysis of Referral Cases with Growth Failure and Clinical Suspicion of having Chromosomal Abnormality

  Background and Objective: Failure to thrive (FTT) is a sign that describes a particular problem rather than a diagnosis and explain growth failure or more advanced failure to gain weight appropriately. The aim of this study was to determine the prevalence and type of chromosomal abnormalities in patients presented with FTT. Materials and Method: One hundred FTT cases with clinical impressio...
