UniProtKB/Swiss-Prot : 73 Neurodegeneration, early-onset, with choreoathetoid movements and microcytic anemia: An autosomal recessive disorder characterized by severe neurological and extra-neurological manifestations. Clinical features include early-onset global developmental delay, absent speech, dystonia, spasticity, choreoathetoid movement disorder, seizures, and microcytic hypochromic anaemia unresponsive to iron supplementation.

MalaCards based summary : Neurodegeneration, Early-Onset, with Choreoathetoid Movements and Microcytic Anemia, is also known as ndcama. An important gene associated with Neurodegeneration, Early-Onset, with Choreoathetoid Movements and Microcytic Anemia is IREB2 (Iron Responsive Element Binding Protein 2). Affiliated tissues include eye, and related phenotypes are global developmental delay and eeg abnormality

OMIM : 56 Early-onset neurodegeneration with choreoathetoid movements and microcytic anemia (NDCAMA) is an autosomal recessive disorder characterized by severe psychomotor developmental abnormalities, abnormal movements, and functional iron deficiency (Costain et al., 2019). (618451)
