ATR-16 syndrome patients have a 1-2Mb deletion on the top of the chromosome 16 p-arm and are associated with a Mendelian inheritance of a-thalassemia. [7] ATR-X syndrome patients have no deletion in chromosome 16, a-thalassemia is rare, and this syndrome is consistent with X-linked recessive inheritance. [8]
β thalassemia major (Mediterranean anemia or Cooley anemia) is caused by a β o /β o genotype. No functional β chains are produced, and thus no hemoglobin A can be assembled. This is the most severe form of β-thalassemia. β thalassemia intermedia is caused by a β + /β o or β + /β + genotype. In this form, some hemoglobin A is produced.
Beta-thalassemia; Other names: Microcytemia, beta type [1] Beta thalassemia genetics, the picture shows one example of how beta thalassemia is inherited. The beta globin gene is located on chromosome 11. A child inherits two beta globin genes (one from each parent). Specialty: Hematology: Types: Thalassemia minor, intermediate and major [2] Causes
Though only definitively diagnosable by genetic sequence testing, including a G band analysis, ATR-16 syndrome may be diagnosed from its constellation of symptoms. It must be distinguished from ATR-X syndrome, a very similar disease caused by a mutation on the X chromosome, and cases of alpha-thalassemia that co-occur with intellectual disabilities with no underlying genetic relationship.
Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are generally single-gene disorders and, in most cases, they are inherited as autosomal recessive traits.
Anemia experienced by some thalassemia intermedia patients are also regarded transfusion dependent. Therefore, most transfusion-dependent thalassemia patients can be diagnosed within the first few years of life, which severe anemia, differed growth, jaundice and hepatosplenomegaly can be observed. Parameters for confirmation includes baseline ...
A screening policy exists in Cyprus to reduce the incidence of thalassemia, which since the program's implementation in the 1970s (which also includes pre-natal screening and abortion) has reduced the number of children born with the hereditary blood disease from 1 out of every 158 births to almost zero.

Delta-beta thalassemia is autosomal recessive disorder, [1] which means both parents are affected and two copies of the gene must be present. [5] A carrier gets a normal gene to produce hemoglobin A, from one parent and the other parent supplies a gene which makes no hemoglobin A. [6] Delta-beta thalassemia is considered rare. [2]
