Benefits and limitations of a multidisciplinary approach to individualized management of Cornelia de Lange syndrome and related diagnoses.

Given the clinical complexities of Cornelia de Lange Syndrome (CdLS), the Center for CdLS and Related Diagnoses at The Children's Hospital of Philadelphia (CHOP) and The Multidisciplinary Clinic for Adolescents and Adults at Greater Baltimore Medical Center (GBMC) were established to develop a comprehensive approach to clinical management and research issues relevant to CdLS. Little work has been done to evaluate the general utility of a multispecialty approach to patient care. Previous research demonstrates several advantages and disadvantages of multispecialty care.

Morpholino-mediated knockdown of ERα, ERβa, and ERβb mRNAs in zebrafish (Danio rerio) embryos reveals differential regulation of estrogen-inducible genes.

Genetically distinct estrogen receptor (ER) subtypes (ERα and ERβ) play a major role in mediating estrogen actions in vertebrates, but their unique and overlapping functions are not entirely clear. Although mammals have 1 gene of each subtype (ESR1 and ESR2), teleost fish have a single esr1 (ERα) and 2 esr2 (ERβa and ERβb) genes. To determine the in vivo role of different ER isoforms in regulating estrogen-inducible transcription targets, zebrafish (Danio rerio) embryos were microinjected with esr-specific morpholino (MO) oligonucleotides to disrupt splicing of the exon III/intron III junction in the DNA-binding domain.
