Partial trisomy 5 with a carrier parent t(5p-;9p+)

Abstract

The significance of partial trisomies of the B group is unknown. An infant with multiple congenital anomalies had a partial trisomy 5p+ syndrome. The father of this patient demonstrated a 5/9 translocation carrier state. A discussion of the relationship of the partial 5p+ syndrome to the Cri du chat syndrome is noted. Partial trisomy 5 does not yet appear to represent a clearly definable syndrome.
