Abstract
Monosomy 18p syndrome is one of the prototypical examples of autosomal terminal deletions. This deletion can be the consequence of de novo deletions, malsegregation of a balanced parental translocation, cryptic subtelomeric deletions or ring chromosome 18. The present case is a rare cytogenetic variant of monosomy 18 as a consequence of whole-arm translocation between chromosomes 13 and 18 which has been reported only three times previously.
