Comment on variant

Chromosomal microarray analysis identified a 6.3 Mb interstitial duplication of the short arm of chromosome 17. The duplication encompasses the dosage sensitive genes, RAI1 and PMP22, associated with Potocki-Lupski syndrome (PTLS, OMIM # 610883) and Charcot-Marie-Tooth disease type 1A (CMT1A, OMIM #118220), respectively. In addition to the 6.3 Mb duplication, there are several additional copy number changes in this region of 17p, separated by regions with a normal copy number state. This pattern suggests the presence of a complex chromosomal rearrangement.
