A boy with partial dup(18q)/del(18p) due to a maternal pericentric inversion: Genotype-phenotype correlation and risk of recombinant chromosomes based on systematic review of the literature.

Abstract excerpt

We report a boy carrying a recombinant chromosome 18, with terminal deletion of 10.8 Mb from 18p11.32 to 18p11.21 and a terminal duplication of 22.8 Mb from 18q21.31 to 18q23, resulting from a maternal pericentric inversion of the chromosome 18. He presented with poor growth, developmental delay, facial dysmorphisms, surgically repaired left cleft lip and palate, a mild form of holoprosencephaly characterized by...
