Case report of newborn with <bold><italic>de novo</italic></bold> partial trisomy 2q31.2-37.3 and monosomy 9p24.3.

We describe a newborn female with a <italic>de novo</italic> duplication of chromosomes 2q31.2 and 2q37.3, and a <italic>de novo</italic> monosomy 9p24.3. The clinical findings of this patient include congenital heart defects, dysmorphic facial features, hypotonia, feeding difficulties and microcephaly. Ultrasonographic prenatal findings were negative for foetal malformations. Only a mild pyelectasis was reported. This is the first report of molecular cytogenetic characterization of a partial trisomy 2q31.2-37.3 with monosomy 9p24.3. [ABSTRACT FROM AUTHOR]
