Genes affect our susceptibility to almost all diseases, from the rare single gene disorders such as cystic fibrosis to common multifactorial disorders such as asthma. They also influence our response to specific therapies. Scientific advances in genetics, starting with projects such as the mapping of the human genome [International Human Genome Sequencing Consortium. Finishing the euchromatic sequence of the human genome. Nature 2004; 431: 931–945] are likely to improve healthcare in the coming decades. Internationally, government initiatives have been established to address strategies to implement these changes [NHS Genetics White Paper. “Our Inheritance – Our Future”: Realising the potential of Genetics in the NHS. UK: Department of Health 2003; Family Health History Initiative. National Human Genome Research Institute and Office of Surgeon General, Department of Health and Human Services. 2004]. A knowledge of basic genetic principles and familiarity with genetic ‘jargon’ associated with new technologies will be important for those practicing in this era of ‘genomic medicine’ [Collins FS, Green ED, Guttmacher AE, Guyer MS. A vision for the future of genomics research. Nature 2003; 422; April 24; 835-847]. The aim of this article is to review genetic terminology using examples from paediatric respiratory medicine. 相似文献

Introduction
Comorbid obsessive-compulsive personality disorder (OCPD) is well-described in obsessive-compulsive disorder (OCD). It remains unclear, however, whether OCPD in OCD represents a distinct subtype of OCD or whether it is simply a marker of severity in OCD.Materials and methods
The aim of this study was to compare a large sample of OCD subjects (n = 403) with and without OCPD on a range of demographic, clinical and genetic characteristics to evaluate whether comorbid OCPD in OCD represents a distinct subtype of OCD, or is a marker of severity.Results
Our findings suggest that OCD with and without OCPD are similar in terms of gender distribution and age at onset of OC symptoms. Compared to OCD − OCPD (n = 267, 66%), those with OCD + OCPD (n = 136, 34%) are more likely to present with the OC symptom dimensions which reflect the diagnostic criteria for OCPD (e.g. hoarding), and have significantly greater OCD severity, comorbidity, functional impairment, and poorer insight. Furthermore there are no differences in distribution of gene variants, or response to treatment in the two groups.Conclusion
The majority of our findings suggest that in OCD, patients with OCPD do not have a highly distinctive phenomenological or genetic profile, but rather that OCPD represents a marker of severity. 相似文献
