Identification of Y chromosomal material in turner syndrome by Fluorescence in Situ Hybridisation (FISH)

Turner syndrome is one of the most common chromosomal abnormalities affecting newborn females. More than half of patients with Turner syndrome have a 45X karyotype. The rest of the patients may have structurally abnormal sex chromosomes or are mosaics with normal or abnormal sex chromosomes. Mosa...
