Quest for quality: department of laboratory medicine and pathology, Mayo Clinic.

This article describes our journey for quality in the Department of Laboratory Medicine and Pathology (DLMP) at Mayo Clinic. It provides the background of the department and the process for the development and implementation of the quality program. In addition, a quality conference and the development of a quality school are outlined. Throughout the course of this process, valuable lessons were learned and are discussed. We are pleased with the success of the quality journey. However, we realize that the quest has just begun. We look forward to the future and the challenges that lie ahead.     

Single suture craniosynostosis: Identification of rare variants in genes associated with syndromic forms

We report RNA‐Sequencing results on a cohort of patients with single suture craniosynostosis and demonstrate significant enrichment of heterozygous, rare, and damaging variants among key craniosynostosis‐related genes. Genetic burden analysis identified a significant increase in damaging variants in ATR, EFNA4, ERF, MEGF8, SCARF2, and TGFBR2. Of 391 participants, 15% were found to have damaging and potentially causal variants in 29 genes. We observed transmission in 96% of the affected individuals, and thus penetrance, epigenetics, and oligogenic factors need to be considered when recommending genetic testing in patients with nonsyndromic craniosynostosis.
