New Haven Conn., April 18, 2012 /PRNewswire/ — JS Genetics announces the launch of XCAT-FX, its propitiatory buccal swab test for the detection of Fragile X syndrome. Fragile X syndrome is the most common cause of inherited intellectual disability (mental retardation) in males and a leading cause of infertility and Fragile X-associated primary ovarian insufficiency in females. Fragile X is also the most common known genetic (single gene) cause of autism. This PCR based test can identify Fragile X in both males and female patients.

The result of XCAT-FX will typically be available within 3 business days following the receipt of the samples at JS Genetics’ CLIA certified, CAP accredited laboratory.

“I am very pleased that we are now including Fragile X in the JS Genetics diagnostic menu,” stated Henry Rinder MD, Medical Director of JS Genetics. “Fragile X testing will further enhance our laboratory’s ability to aid physicians in making the sometimes difficult diagnosis of disorders of sex chromosomes, which also include Turner and Klinefelter syndromes and related sex chromosome aneuploidies.”
