Gross rearrangements in the MECP2 gene in three patients with Rett syndrome: implications for routine diagnosis of Rett syndrome.

Abstract excerpt

Since 1999, many laboratories have confirmed that mutations in the MECP2 gene are the primary cause of Rett syndrome (RTT or RS) and identified mutations in 70 to 90% of the sporadically affected girls. Most of the screenings are PCR-based and restricted to the coding part of the gene and therefore prone to miss gross rearrangements. By Southern blot analysis we identified large deletions (>1 kb) in three female...
