Klinefelter syndrome (XXY) and XYY syndrome are examples of sex abnormalities found in male karyotypes while Turner syndrome (X0) and triple X syndrome are the examples of sex abnormalities found in female karyotypes. The missing gene prevents the body from growing and developing normally. Often, a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen at birth. Individuals with a mosaic 45,X/46,XY genotype have a variety of phenotypic presentations ranging from male to female which are not correlated with the perce… - Neurofibromatosis 1 Typically, these men have dysmorphic features such as webbed neck, short stature, low-set ears and wide-set eyes. What is Turner syndrome? Gonadal dysgenesis is seen in the vast majority of cases, and almost all affected individuals are infertile (Sybert and McCauley 2004). We aimed to investigate change over time in incidence, prevalence and age at diagnosis among Turner syndrome (TS), Klinefelter syndrome (KS), Triple X syndrome (Triple X) and Double Y syndrome (Double Y). Patients with Turner syndrome, often develop ear infections that can lead to deafness, also develop hypothyroidism or hyperthyroidism. The cause is a missing or incomplete X chromosome (the chromosome that determines a person’s sex before birth). The male karyotype testing is done to identify the chromosomal aberrations present in males which is characterized by the 23 rd chromosome pair consisting of an X and a Y chromosome and the female karyotypes reveal information on chromosomal aberrations of females which is characterized by the 23 rd chromosome pair having two X chromosomes in it. The human body has 46 (or 23 paired) chromosomes that store genetic material. Noonan syndrome occurs in both males and females with a normal karyotype (46,XX and 46,XY). In patients with Turner syndrome, speech is not affected, but there is a motor deficit. In conclusion, the majority of the sSMCs in patients with a mos 45,X/46,X,+mar karyotype were derived from the sex chro-mosomes. The molecular cytogenetic features of sSMCs may provide useful information for genetic counseling, prenatal It was noted that 15 of 1000 … Is practice amniocentesis for fetal karyotype analysis.
