Summaries for Anemia, Sideroblastic, and Spinocerebellar Ataxia

GARD : 20 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 2802 Definition X-linked sideroblastic anemia and ataxia (XLSA-A) is a rare syndromic, inherited form of sideroblastic anemia (see this term) characterized by mild to moderate anemia (with hypochromia and microcytosis) and early-onset, non- or slowly progressive spinocerebellar ataxia. Epidemiology The prevalence is unknown. Only 10 genetically confirmed patients have been reported to date. Clinical description XLSA-A usually presents before the age of 3 years. Anemia is usually asymptomatic. In males, spinocerebellar symptoms are apparent in childhood and can include delayed walking, predominantly truncal ataxia, dysmetria and dysdiadochokinesis. Dysarthria and intention tremor are sometimes present. Ataxia may improve over time, but in the fifth to sixth decade of life a slow deterioration of walking is noted. Upper motor neuron signs in the legs such as equivocal or extensor plantar responses, brisk deep tendon reflexes and unsustained ankle clonus are sometimes present. Strabismus, as well as mild learning disability and depression, have also been reported in some, but intellectual abilities are generally within the normal range. Hepatic and systemic iron overload does not occur. Females are clinically asymptomatic. Etiology XLSA-A is caused by mutations in the ABCB7 gene (Xq13.3), encoding a mitochondrial ATP-binding cassette (ABC) transporter protein, which plays a role in heme production and iron homeostasis. A mutation in this gene alters the availability of reduced iron and therefore disrupts heme biosynthesis. The ABCB7 gene is highly expressed in both the bone marrow and the cerebellum, which may explain ataxia. Diagnostic methods Diagnosis is based on the presence of characteristic neurological and blood test findings. Mild to moderate hypochromic, microcytic anemia is noted in all males and both whole blood total erythrocyte protoporphyrin (TEP) and zinc erythrocyte protoporphyrin (ZnEP) are elevated. Bone marrow examination demonstrates the presence of increased iron stores with ring sideroblasts and peripheral blood smear reveals Pappenheimer bodies. In the majority of cases magnetic resonance imaging (MRI) shows cerebellar atrophy/hypoplasia. Female carriers display hematological abnormalities. Molecular genetic testing identifies a ABCB7 gene mutation, confirming the diagnosis. Differential diagnosis The main differential diagnosis includes other forms/causes of ataxia that typically present before the age of 3 years such as ataxia-telangiectasia, infantile-onset spinocerebellar ataxia, congenital disorder of glycosylation, and cerebellar malformations (e.g. Dandy-Walker malformation) (see these terms). Ataxia with vitamin E deficiency, Friedreich ataxia, ataxia - oculomotor apraxia type 1 and 2, and X linked sideroblastic anemia (see these terms), the most common form of congenital sideroblastic anemia (without ataxia), should also be excluded. Antenatal diagnosis Prenatal testing is possible in families with a known ABCB7 mutation. Genetic counseling XLSA-A is inherited in an X-linked recessive manner and genetic counseling is possible. Males who inherit the mutation from their mother will be affected while females who inherit the mutation from their father or mother will be carriers and are clinically asymptomatic. Management and treatment There is no cure for XLSA-A and treatment is symptomatic. Anemia does not require treatment. Early physical therapy may aid in the acquisition of gross motor skills. Ankle fixation orthoses and walkers may be required to aid with mobility. Weighted eating utensils promote independent skills in children. Speech therapy is recommended for those with dysarthria. Crutches or a wheelchair may be needed by some patients. Prognosis While prognosis information is limited due to very few existing reports, XLSA-A does not appear to have a significant impact on life expectancy. Quality of life, however, can be significantly affected.

MalaCards based summary : Anemia, Sideroblastic, and Spinocerebellar Ataxia, also known as x-linked sideroblastic anemia with ataxia, is related to microcytic anemia and sideroblastic anemia, and has symptoms including clonus, dysdiadochokinesis and action tremor. An important gene associated with Anemia, Sideroblastic, and Spinocerebellar Ataxia is ABCB7 (ATP Binding Cassette Subfamily B Member 7), and among its related pathways/superpathways are Biosynthesis of cofactors and Porphyrin and chlorophyll metabolism. The drugs Citalopram and Methylphenidate have been mentioned in the context of this disorder. Affiliated tissues include bone marrow, eye and whole blood, and related phenotypes are neurological speech impairment and nystagmus

Disease Ontology : 12 A sideroblastic anemia that is characterized by decreased production of hemoglobin and ataxia and has material basis in the mutation in the ABCB7 gene.

MedlinePlus Genetics : 43 X-linked sideroblastic anemia and ataxia is a rare condition characterized by a blood disorder called sideroblastic anemia and movement problems known as ataxia. This condition occurs only in males.Sideroblastic anemia results when developing red blood cells called erythroblasts do not make enough hemoglobin, which is the protein that carries oxygen in the blood. People with X-linked sideroblastic anemia and ataxia have mature red blood cells that are smaller than normal (microcytic) and appear pale (hypochromic) because of the shortage of hemoglobin. This disorder also leads to an abnormal accumulation of iron in red blood cells. The iron-loaded erythroblasts, which are present in bone marrow, are called ring sideroblasts. These abnormal cells give the condition its name. Unlike other forms of sideroblastic anemia, X-linked sideroblastic anemia and ataxia does not cause a potentially dangerous buildup of iron in the body. The anemia is typically mild and usually does not cause any symptoms.X-linked sideroblastic anemia and ataxia causes problems with balance and coordination that appear early in life. The ataxia primarily affects the trunk, making it difficult to sit, stand, and walk unassisted. In addition to ataxia, people with this condition often have trouble coordinating movements that involve judging distance or scale (dysmetria) and find it difficult to make rapid, alternating movements (dysdiadochokinesis). Mild speech difficulties (dysarthria), tremor, and abnormal eye movements have also been reported in some affected individuals.
