CONSTITUTIONAL MEGALOBLASTIC ANEMIA WITH SEVERE NEUROLOGIC DISEASE

Alternate names

CONSTITUTIONAL MEGALOBLASTIC ANEMIA WITH SEVERE NEUROLOGIC DISEASE Is also known as dihydrofolate reductase deficiency, dhfr deficiency

Description

Dihydrofolate reductase deficiency is an autosomal recessive metabolic disorder characterized by the hematologic findings of megaloblastic anemia and variable neurologic symptoms, ranging from severe developmental delay and generalized seizures in infancy (Banka et al., 2011) to childhood absence epilepsy with learning difficulties to lack of symptoms (Cario et al., 2011). Treatment with folinic acid can ameliorate some of the symptoms.

Most common symptoms of CONSTITUTIONAL MEGALOBLASTIC ANEMIA WITH SEVERE NEUROLOGIC DISEASE

  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Microcephaly
  • Ataxia
