Genetic testing and genotype-phenotype analysis for a child with X-linked hypohidrotic ectodermal dysplasia / 中华医学遗传学杂志

OBJECTIVE@#To carry out genetic testing for a Chinese patient with X-linked hypohidrotic ectodermal dysplasia (XLHED) and explore its genotype-phenotype correlation.@*METHODS@#Clinical data of the patient was collected. Peripheral blood samples were taken from the patient, his parents and 100 unrelated healthy controls. Genetic variants were detected by using next-generation sequencing using a skin-disease panel through targeted capture and next generation sequencing. Candidate variant was verified by Sanger sequencing. All literature related to genetic testing of XLHED patients in China was searched in the database, and the genotypes and phenotypes of patients in the literature and the correlation between them were statistically analyzed.@*RESULTS@#A novel splice site variant c.655_689del was detected in the patient but not among his parents and the 100 unrelated healthy controls. So far 61 variants of the EDA gene have been identified among Chinese patients with XLHED, which suggested certain degree of genotype-phenotype correlation.@*CONCLUSION@#A novel c.655_689del variant has been identified in the EDA gene, which has expanded the spectrum of EDA gene variant and facilitated delineation of the genotype-phenotype correlation of XLHED.

Physiology and genomics: toward systems biology / 生理学报

The last ten years have seen an unprecedented merge of physiology and genomics. While the field of physiological genomics is still very young, the introduction of the concept of systems biology promises to propel physiological genomics to a whole new level. In this brief article, we outlined some of the great opportunities and challenges for physiologists at this exciting time of physiological sciences, and used our own experience from the last ten years as an example to discuss how we could expand and go beyond the combination of physiology and genomics to achieve a systems understanding of biology.
