We describe a 10-month-old boy with 22q13 deletion syndrome. Chromosomal analysis showed a partial duplication of 22p11.2-pter and a terminal deletion of 22q13.31-qter. Maternal chromosomal analysis showed a pericentric inversion of chromosome 22, with breakpoints at p11.2 and q13.31 [inv(22)(p11.2q13.31)]. The deleted chromosome resulted from a recombinant chromosome inherited from his mother. This is a rare case of 22q13 deletion syndrome associated with parental pericentric inversion of chromosome 22.
