  • Phenotype Manifestations of Polysomy X at Males
    PHENOTYPE MANIFESTATIONS OF POLYSOMY X AT MALES Amra Ćatović* &Centre for Human Genetics, Faculty of Medicine, University of Sarajevo, Čekaluša , Sarajevo, Bosnia and Herzegovina * Corresponding author Abstract Klinefelter Syndrome is the most frequent form of male hypogonadism. It is an endocrine disorder based on sex chromosome aneuploidy. Infertility and gynaecomastia are the two most common symptoms that lead to diagnosis. Diagnosis of Klinefelter syndrome is made by karyotyping. Over years period (-) patients have been sent to “Center for Human Genetics” of Faculty of Medicine in Sarajevo from diff erent medical centres within Federation of Bosnia and Herzegovina with diagnosis suspecta Klinefelter syndrome, azoo- spermia, sterilitas primaria and hypogonadism for cytogenetic evaluation. Normal karyotype was found in (,) subjects, and karyotype was changed in (,) subjects. Polysomy X was found in (,) examinees. Polysomy X was expressed at the age of sexual maturity in the majority of the cases. Our results suggest that indication for chromosomal evaluation needs to be established at a very young age. KEY WORDS: polysomy X, hypogonadism, infertility Introduction Structural changes in gonosomes (X and Y) cause different distribution of genes, which may be exhibited in various phenotypes. Numerical aberrations of gonosomes have specific pattern of phenotype characteristics, which can be classified as clini- cal syndrome. Incidence of gonosome aberrations in males is / male newborn (). Klinefelter syndrome is the most common chromosomal disorder associated with male hypogonadism. According to different authors incidence is / male newborns (), /- (), and even / (). Very high incidence indicates that the zygotes with Klinefelter syndrome are more vital than those with other chromosomal aberrations.

Yonago We have developed a new polymerase chain reaction(PCR)-based method for detection of the CGG repeat in FMR-1 gene. No specific product from PCR was detected on the gel with ethidium bromide staining, because 7-deaza-2'-dGTP is necessary for amplification of this repeat. Biotin-labeled primer was used for PCR and the product was transferred to a nylon membrane followed the detection of biotin by Smilight kit. The size of PCR product from normal control were slightly various and around 300bp. No PCR product was detected from 3 fragile X male patients in 2 families diagnosed by cytogenetic examination. This method is useful for genetic screen- ing of male mental retardation patients to exclude the fragile X mutation.

  • Rare Double Aneuploidy in Down Syndrome (Down- Klinefelter Syndrome)
    Research Article Journal of Molecular and Genetic Volume 14:2, 2020 DOI: 10.37421/jmgm.2020.14.444 Medicine ISSN: 1747-0862 Open Access Rare Double Aneuploidy in Down Syndrome (Down- Klinefelter Syndrome) Al-Buali Majed J1*, Al-Nahwi Fawatim A2, Al-Nowaiser Naziha A2, Al-Ali Rhaya A2, Al-Khamis Abdullah H2 and Al-Bahrani Hassan M2 1Deputy Chairman of Medical Genetic Unite, Pediatrics Department, Maternity Children Hospital Al-hassa, Hofuf, Saudi Arabia 2Pediatrics Resident, Pediatrics Department, Maternity Children Hospital Alhassa, Hofuf, Saudi Arabia Abstract Background: The chromosomal aneuploidy described as Cytogenetic condition characterized by abnormality in numbers of the chromosome. Aneuploid patient either trisomy or monosomy, can occur in both sex chromosomes as well as autosome chromosomes. However, double aneuploidies involving both sex and autosome chromosomes relatively a rare phenomenon. In present study, we reported a double aneuploidy (Down-Klinefelter syndrome) in infant from Saudi Arabia. Materials and Methods: In the present investigation, chromosomal analysis (standard chromosomal karyotyping) and fluorescence in situ hybridization (FISH) were performed according to the standard protocols. Results: Here, we report a single affected individual (boy) having Saudi origin, suffering from double chromosomal aneuploidy. The main presenting complaint is the obvious dysmorphic features suggesting Down syndrome. Chromosomal analysis and FISH revealed 48,XXY,+21, show the presence of three copies of chromosome 21, two copies of X chromosome and one copy of Y chromosome chromosomes. Conclusion: Patients with Down syndrome must be tested for other associated sex chromosome aneuploidies. Hence, proper diagnosis is needed for proper management and the cytogenetic tests should be performed as the first diagnostic approach.

  • Turner Syndrome
    Sex Chromosome Abnormalities Turner Syndrome Turner syndrome occurs in 1/2500 live births. It is caused by a partial or complete absence of one of the X chromosomes in a female. A single X chromosome is the most common cause of miscarriage. It is believed 99% of all 45,X conceptions result in miscarriage. The fetuses are often severely hydropic (Figure 1). When a baby is born with Turner syndrome there are often few features. One feature that can be noted during the newborn period is puffy hands and puffy feet (Figure 3). Broad chest can also be an early sign. The majority of females have normal intelligence. There are some deficits in visual special abilities. Most females with Turner syndrome present at age 5-6 with short stature. Features include short stature, webbing of the neck, shield chest, shortened 4 th metacarpal and madelung deformity of the forearm. There is also a risk of renal anomalies including horseshoe kidneys. Adolescent girls with Turner syndrome often have failure of puberty, absence of spontaneous breast development and primary amenorrhea. Approximately 60% of females with Turner syndrome have a single X chromosome in all cells analyzed (Figure 2). Twenty percent are mosaic in which some of their cells have 2 X chromosomes while some have a single X. A small percentage of females with Turner syndrome have a part of one X chromosome in a ring formation. These females are at risk of developmental delay. Figure 1. Figure 2. Figure 3. Patients with Turner syndrome are at increased risk for a number of medical issues including renal anomalies (most common horseshoe kidneys), hearing impairment, and congenital heart defects.

Many males are not diagnosed until puberty or chromosome. Chromosomes, found in all body cells, contain adulthood. As many as two-thirds of men with the syndrome may genes. Genes provide specific instructions for body characteristics never be diagnosed. Many men with mosaic Klinefetler syndrome and functions. For example, some genes determine height and have few obvious signs except very small testicles. hair color. Other genes influence language skills and reproductive functions. Each person typically has 23 pairs of chromosomes. One of these pairs (sex chromosomes) determines a person’s sex. A baby with two X chromosomes (XX) is female. A baby with one X chromosome and one Y chromosome (XY) is male. Most males with Klinefelter syndrome, also called XXY males, have two X chromosomes instead of one. The extra X usually occurs in all body cells. Sometimes the extra X only occurs in some cells, resulting in a less severe form of the syndrome (called mosaic Klinefelter syndrome). Rarely, a more severe form occurs when there are two or more extra X chromosomes. DID YOU KNOW? Klinefelter syndrome is the most common sex-chromosome abnormality, affecting about one in every 500 to 700 men. WHAT CAUSES KLINEFELTER SYNDROME?

Despite the discovery of many mutations in various retinopathies, a large part of patients remain undiagnosed genetically. Targeted next generation sequencing of the human genome is a suitable approach for retinopathy molecular diagnosis. Methods: We described a cohort of 211 families from central China with various forms of retinopathy, 95 families of which were investigated using NGS multi-gene panel sequencing as well as the other 116 patients were LHON suspected tested by Sanger sequencing. We validated the candidate variants by PCR- based Sanger sequencing. We have made comprehensive analysis of the cases through sequencing data and ophthalmologic examination information.
