There are many different types of blood disorders, and whether they are inherited is related to the specific disease.
Most blood disorders are not inherited, but there are some blood disorders that are genetic in nature and have clear genetic characteristics. Examples include hereditary spherocytosis, hereditary glucose-6-phosphate dehydrogenase deficiency, alpha-thalassaemia, abnormal haemoglobinopathy, beta-thalassaemia, haemophilia, and hereditary vascular haemophilia.
