PURPOSE 45,XY,t(13;14)(q10;q10) karyotype can suggest infertility associated with more or less severe oligospermia in male adults. In addition, 45,XX,t(13;14)(q10;q10) karyotype carries reproductive risks such as miscarriage or infertility in female adults. However, reports on the phenotype of this karyotype in children are very rare. This study was done to observe various phenotypes of this ka...

OBJECTIVE Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. METHODS Our ...

A couple was referred for cytogenetic examination due to idiopathic miscarriages. The proband proved to be a carrier of chromosomal translocation and her partner's karyotype was found to be normal. The karyotype of the proband is 46,XX,t(4;22)(q23;q11.2) and can be regarded as a reason of fertility problems in the investigated couple. The risk of further miscarriages is high, but the risk of a ...

One of the most popular, cheap and widely used approaches in comparative cytogenetics - especially by botanists - is that concerning intrachromosomal and interchromosomal karyotype asymmetry. Currently, there is no clear indication of which method, among the many different ones reported in literature, is the most adequate to infer karyotype asymmetry (especially intrachromosomal), above all in ...

conclusions the young woman with turner syndrome have several risk factors for early coronary artery disease development. in such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment. case presentation the patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. she was diagnosed wit...

Turner syndrome is a sex-chromosome disorder occurring in one out of 2500 female births and characterized by growth retardation, gonadal dysgenesis and cardiovascular anomalies. The 45, XO karyotype is the most frequent type of this disease. Herein, we report on a 6-year-old girl with Turner syndrome and 45, XO karyotype presenting with short stature. She had dextrocardia and hiatal hernia. To ...

Karyotype and chromosomal localization of major (18-5.8-28S) and minor (5S) ribosomal RNA genes were studied in two species of Pectinidae, zhikong (Chlamys farreri) and bay (Argopecten irradians irradians) scallops, using fluorescence in situ hybridization (FISH). C. farreri had a haploid number of 19 with a karyotype of 3m + 4sm + 7sm-st + 4st + 1st-t, and A. i. irradians had a haploid number ...
