Coffin‐Lowry syndrome in a girl with 46,XX,t(X;11)(p22;p15)dn: Identification of RPS6KA3 disruption by whole genome sequencing

摘要

We report a Japanese girl with Coffin‐Lowry syndrome phenotype such as hypertelorism, hypodontia, and tapering fingers and 46,XX,t(X;11)(p22;p15)dn. Whole genome sequencing revealed RPS6KA3 disruption by the translocation, and X‐inactivation analysis indicated preferential inactivation of the normal X chromosome. The results explain the development of an X‐linked disease in this girl.
