    Journal: Zhong Nan Da Xue Xue Bao Yi Xue Ban; 2005 Dec; 30(6):657-9. PubMed ID: 16708803.
    Abstract:
    OBJECTIVE: To investigate the source of the extra small chromosome in a patient with karyotype 45,X[115]/46,X + mar[45]/46,XY[29]. METHODS: The SRYgene was detected by PCR, and the chromosome Y probe that labeled with biotin was detected by fluorescence in situ hybridization. RESULTS: SRY gene is detected positive and the mar chromosome showed positive signal with FISH in human chromosome Y probe pool. CONCLUSION: The extra small chromosome is part of the chromosome Y.
