title: Franceschetti syndrome in a child with a de novo balanced translocation (5;13)(q11;p11) and significant decrease of hexosaminidase B.
abstract: We report a previously undescribed case of a de novo balanced translocation t(5;13)(q11;p11) and Franceschetti syndrome in a 3-year-old girl. The hypothesis that this unusual association might not be coincidental but rather due to position effect is proposed. Moreover the significant decrease of hexosaminidase B activity suggests the localization of this gene on the 5q11 band.
