First published in 1966, Thompson and Thompson Genetics and Genomics in Medicine has become an essential textbook for medical students, genetic counseling students, students in laboratory medicine, and more advanced trainees. With its focus on fundamental principles in human genetics and genomics and their application to medicine, the book has served many as a well-thumbed resource they return to over and over. Such students can continue to depend on this valuable text, joining those in newer fields of genome data analysis for all they need to know about genetics and genomics throughout their basic science training, clinical placements and beyond. Coverage includes new discoveries-such as the functional roles of non-coding RNAs, chromatin regulation and epigenetics-latest technologies, and new diagnoses they are enabling. Under an expanded title, this ninth edition has been completely revised by a new editorial team overseeing a large cadre of contributing authors. Support groups have also assisted to update illustrations featuring beautiful images of those living with genetic conditions. Comprehensive coverage of: genomes in biology and medicine; copy number and structural genomic variation; novel discoveries; latest technology; and new genetic diagnosesOver 40 clinical case studies, capturing the latest challenges of variable expression, pleiotropy, and complex disorders through new diagnostic strategiesFull-color text, illustrations, updated line diagrams, and clinical photosEnd-of-chapter questions and comprehensive answers to challenge the reader to consolidate the material into practice and prepare for examinationAn enhanced eBook version is included with purchase.
