    The main clinical features of the 7 year old boy were MR, growth reduction, peripheral motor ans sensory neuropathy, hypoplastic cerebellar vermis, zonular cataract, and body asymmetry.
    The etxra chromosome 17 probably originated from a postzygotic mitotic nondisjunction of the maternal chromosome 17. No evidence of UPD was found.

AJMG Part A: DOI=10.1002/ajmg.a.31319; 140A: 1628-1636, 2006. [PubMed: 16802327]
    Four new cases are presented and data on 23 previously reported cases are reviewed.
    46XX/XY/47,XX/XY+17. FISH confirmed trisomy 17 in all of the four cases.
    It was found that in only 5/23 instances mosaicism has been demonstrated in lymphocytes and/or fibroblasts, and in only these have MCA , facial dysmorphisms, and MR have been reported. No consistent phenotype emerges and the clinical significance of trisomy 17 mosaicism in amniocentesis and cvs remains uncertain.
    The trisomy cell line is rarely found in lymphocytes, hence cordocentesis is not indicated.
