    46,XX,t(3;17)(q26.3;q23.1)de novo.
    The CLS syndrome was present in this infant with severe limb reduction defect.
    The 1995 letter to the editor shows FISH data indicating trisomy for 3q26.3 by probe 886e7 (CEPH). The NAALADL2 gene, spans 1.37 Mb, was at the 3q26.3 breakpoint location. The 2004 study strongly suggests that this gene is not involved in the pathogenesis of CdLS.
    Aberration: Reciprocal translocation
    MIM#: 122470
    Index Terms: Limb reduction defect
    Positive band
