Sister chromatid exchanges and structural chromosome aberrations in relation to age and sex

Human Genetics, 1982
Sister chromatid exchanges (SCE) and structural chromosome aberrations were analyzed in peripheral blood lymphocytes of 100 individuals, and correlated to age and sex. No correlation was found between the frequency of SCE and age, but older individuals had significantly more structural aberrations than younger.

Age-related effects on sex chromosome aberrations in equine spermatozoa

Journal of Equine Veterinary Science, 2014
Many chromosomal anomalies resulting from meiotic disorders lead to the formation of gametes that are incapable of reproductive function and are spontaneously eliminated. However, formation of a zygote with structurally or numerically abnormal genome most often produces a lethal effect early in fetal life.

[Undescended testis and hypospadia in sex chromosomal aberrations].

Klinische Padiatrie, 1999
If hermaphrodite genitals are present in the patient or a higher degree of hypospadia is shown with maldescensus testis, a chromosomal disorder must be considered as one potential cause of the anomaly. The case report of a child with cryptorchidism on the right, inguinal testis on the left and penoscrotal hypospadia is presented as an example. A mosaic

Aberrations of sex chromosomes in the patients with menstruation problems

Journal de Gynecologie Obstetrique et Biologie de la Reproduction, 1990
<p>We studied 150 women with primary/secondary amenorrhea and/or oligomenorrhea; in 61 cases we found an abnormal karyotype (i.e. 40.7%): 51 cases in the first group of 110 patients with amenorrhea (i.e. 46%) and 10 cases in the second group of 40 patients with oligomenorrhea and/or secondary amenorrhea (i.e. 25%).

[Sex chromosome aberration with the 48 XYYY karyotype. A case report of the phenotype of a rare sex chromosome aneuploidy].

Zeitschrift fur Kinder- und Jugendpsychiatrie, 1994
This is a case report on a 19-year-old patient with the chromosome constellation 48, XYYY. The patient showed signs of dysmorphism, mental retardation and problems in psychosocial functioning. A literature review revealed that individuals with this karyotype have widely varying phenotypes with regard not only to physical signs but also to brain ...

Aberrant sex chromosome mechanisms in mammals. Evolutionary aspects.

Differentiation; research in biological diversity, 1991
There are a number of mammalian species with complicated or unknown mechanisms for sex determination. The literature is reviewed with special reference to the origin and evolution of the sex chromosome mechanisms in three species of monotremes and in the following species of rodents: the creeping vole (Microtus oregoni), the mole vole (Ellobius ...
