In Klinefelter Syndrome Patients, What are the Common Behavioral Problems?
Discussion Klinefelter syndrome (KS) is a common genetic abnormaly with a prevalence of 1 in ~650 male births. It was first described in 1942 by Dr. Harry Klinefelter. It is associated with at least one extra X chromosome with the most common karyotype (~80% of patients) being 47 XXY. Other karyotypes are seen along with mosaicism. It is believed that although it is very prevalent, only about 25-33% of people with KS are identified. About 10% are identified before puberty with the rest usually identified because of hypogonadism and tall stature especially in teenage years or due to infertility in adulthood. KS is diagnosed...

What Medical Problems Can Patients with Turner Syndrome Have?
Discussion Turner Syndrome (TS) is one of the most common genetic disorders in females. It was first described by Dr. Henry H. Turner in 1938. It affects 1 in 2000-2500 births and ~70,000 girls and women have TS in the United States. It is caused by the absence of all or part of the second X chromosome. The most common variation is 45X which affects about 50% of TS patients and usually has the most complications, but there are other variations. Phenotypes vary and therefore the age of diagnosis varies. Mean age of diagnosis unfortunately is 15 years. Diagnosis is made by chromosomal analysis. Haploinsufficiency of the SHOX...

Detecting Klinefelter Syndrome Disorder in Boys
A new assessment tool is being developed by researchers at Columbia University Medical Center (CUMC) to help pediatricians detect the physical traits of the syndrome. The tool could pave the way for early interventions that prevent and treat a range of physical, psychological, social, and cognitive impairments. The study was published in The Journal of Pediatrics.

sCD163 and sex steroids
Soluble CD163 (sCD163) is linked to low-grade inflammation states, including diabetes, obesity, liver disease, and atherosclerosis, all of which are prevalent in Turner Syndrome (TS) and Klinefelter Syndrome (KS). Thomsen and colleagues assessed the levels and regulation of sCD163 with regard to treatment with sex hormone therapy in males with KS and females with TS. They found that males with KS had higher levels of sCD163 compared with controls and the levels correlated to plasma testosterone. Treatment with testosterone did not significantly lower sCD163. Females with TS not receiving hormone replacement therapy (HRT) h...

Gynecomastia: Prominent Male Breasts
Gynecomastia is a benign male breast condition in which a male has one or two prominent breasts. It is not considered to increase a man's risk of developing male breast cancer. Gynecomastia is not the same as Klinefelter syndrome, but it is one of the symptoms of Klinefelter's. (Source: About.com Breast Cancer)
