Green List (high evidence)

EIF5A is currently not associated with any phenotype in OMIM (last edited on 18/07/2019), but is listed in Gene2Phenotype with a 'probable' disease confidence rating for 'EIF5A-related craniofacial-neurodevelopmental disorder'

- PMID: 33547280 (2021) reports 7 unrelated individuals with different de novo heterozygous variants in the EIF5A gene. Microcephaly was evident at birth in 3/5 individuals, and assessments in later life indicated microcephaly in 5/7 cases (HC ranging between -1.94 and -7.47 SD). Other features include DD/ID and craniofacial dysmorphism, including micrognathia. Supportive functional data included.

Overall sufficient (>3) unrelated cases of microcephaly in patients with EIF5A variants, for inclusion on this panel.
