Panel Version: 9.3
At least 5 unrelated families have been identified with biallelic LOF variants in the EEF1D gene associated with a severe neurodevelopmental disorder. Phenotype is characterised by severe ID/DD and microcephaly but can also include features such as spasticity, optic atrophy, seizures, feeding difficulties, and recurrent aspiration pneumonia.
