| Pathology (details) | Imprinting disorders (IDs) are a group of rare genetic diseases affecting between 7,500 and 10,000 patients in the Europe. They are caused by genetic abnormalities affecting a certain type of gene, known as parental imprinting genes. Most genes in the human body are present in pairs in non-sex cells, each pair being called an allele. The genes that are subject to parental imprinting are different. They have only one allele and are subject to special regulatory mechanisms, called epigenetic modifications. Abnormalities in these mechanisms lead to abnormalities in gene expression leading to a variety of diseases whose clinical expression varies depending on whether the gene is passed on from the father or the mother. They constitute a group of 9 rare diseases (Beckwith-Wiedemann Syndrome, Prader Willi, Angelman, Silver Russel, Familial Precocious Puberty Limited to Boys, Pseudohypoparathyroidism, Kagami-Ogata, Temple, Transient Neonatal Type 1 Diabetes) that are probably underdiagnosed and affect growth, metabolism (lipid, carbohydrate, bone), feeding and social behavior, and reproduction. |
