Bridging the language gap - A call for the wider use of Human phenotype ontology by non-geneticist clinicians when requesting genomic tests

Advances in genomic technology including the development of next-generation sequencing (NGS) have enabled the identification of thousands of variations at a time, allowing the discovery of novel genetic diseases. Given the volume of data generated by these investigations, attention is drawn towards reporting relevant clinical features by clinicians to guide the diagnosis and management of their patients. The Human Phenotype Ontology (HPO) developed in 2008, revolutionized the semantic vocabulary of phenotypic descriptions in genomic medicine allowing researchers, laboratories and clinical geneticists to better understand each other. In this era of personalized medicine where genetic tests are becoming more accessible, non-geneticist clinicians are expected to be more involved than ever in the process of ordering genetic tests and interpreting genetic reports. It is therefore essential that they understand and adequately apply HPO nomenclature to integrate the patient care chain and seize the opportunity offered by this tailored language. The current article highlights the importance of using HPO vocabularies in clinical practice and advocates for its wider use by non-geneticist clinicians. Correct use of HPO will reduce misunderstandings between healthcare professionals and ultimately improve the healthcare system.
