Receptor tyrosine kinase mutations in developmental syndromes and cancer: two sides of the same coin

Laura M. McDonell, Kristin D. Kernohan, Kym M. Boycott, Sarah L. Sawyer
2015 Human Molecular Genetics  
Receptor tyrosine kinases (RTKs) are a family of ligand-binding cell surface receptors that regulate a wide range of essential cellular activities, including proliferation, differentiation, cell-cycle progression, survival and apoptosis. As such, these proteins play an important role during development and throughout life; germline mutations in genes encoding RTKs cause several developmental syndromes, while somatic alterations contribute to the pathogenesis of many aggressive cancers. This
more » ... tes an interesting paradigm in which mutation timing, type and location in a gene leads to different cell signaling and biological responses, and ultimately phenotypic outcomes. In this review, we highlight the roles of RTKs in developmental disorders and cancer. The multifaceted roles of these receptors, their genetic signatures and their signaling during developmental morphogenesis and oncogenesis are discussed. Additionally, we propose that comparative analysis of RTK mutations responsible for developmental syndromes may shed light on those driving tumorigenesis.

Meconium ileus in a Lebanese family secondary to mutations in the GUCY2C gene

Amanda Smith, Dennis E Bulman, Claire Goldsmith, Eric Bareke, Jacek Majewski, Kym M Boycott, Sarah M Nikkel
2014 European Journal of Human Genetics  
Meconium ileus is most often associated with mutations in the CFTR gene; however recently, mutations in GUCY2C in the Bedouin population have also been shown to result in this phenotype. This gene codes for an intestinal transmembrane receptor that generates cyclic GMP, which activates cystic fibrosis transmembrane receptor. We report a third family that supports the association of variants in the GUCY2C gene with meconium ileus (MI). A Lebanese kindred was studied and individuals affected with

New Diagnostic Approaches for Undiagnosed Rare Genetic Diseases

Taila Hartley, Gabrielle Lemire, Kristin D. Kernohan, Heather E. Howley, David R. Adams, Kym M. Boycott
2020 Annual review of genomics and human genetics (Print)  
Accurate diagnosis is the cornerstone of medicine; it is essential for informed care and promoting patient and family well-being. However, families with a rare genetic disease (RGD) often spend more than five years on a diagnostic odyssey of specialist visits and invasive testing that is lengthy, costly, and often futile, as 50% of patients do not receive a molecular diagnosis. The current diagnostic paradigm is not well designed for RGDs, especially for patients who remain undiagnosed after
more » ... initial set of investigations, and thus requires an expansion of approaches in the clinic. Leveraging opportunities to participate in research programs that utilize new technologies to understand RGDs is an important path forward for patients seeking a diagnosis. Given recent advancements in such technologies and international initiatives, the prospect of identifying a molecular diagnosis for all patients with RGDs has never been so attainable, but achieving this goal will require global cooperation at an unprecedented scale. Expected final online publication date for the Annual Review of Genomics and Human Genetics, Volume 21 is August 31, 2020. Please see for revised estimates.
