{Reference Type}: Case Reports {Title}: A Rare Cytogenetic Variant of Monosomy 18p Syndrome as a Consequence of Whole-Arm Translocation between Chromosomes 13 and 18. {Author}: Safavi M;Haghi Ashtiani MT;Badv RS;Azari-Yam A;Vasei M; {Journal}: Arch Iran Med {Volume}: 22 {Issue}: 10 {Year}: 10 2019 1 {Factor}: 3.138 {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.
