LONP1 and CODAS syndrome: Although EVEN‐plus syndrome is extremely rare, it needs to be differentiated from CODAS syndrome, which is a rare autosomal recessive disorder caused by a defect in the LONP1 gene; CODAS also has a similar phenotype of developmental delay, overfolded and shrunken external ears, a flattened and hypoplastic nasal bridge and hypophysis of the extremities.
