Summary

Neurodevelopmental disorder with facial dysmorphism, absent language, and pseudo-Pelger-Huet anomaly (NEDFLPH) is an autosomal recessive disorder characterized by global developmental delay with severely impaired intellectual development. Affected individuals often have behavioral abnormalities and may have variable findings on brain imaging, such as thin corpus callosum. Laboratory studies show nuclear lobulation defects in a subset of neutrophils, indicating a pseudo-Pelger-Huet anomaly (see 169400) and suggesting defects in the integrity of the nuclear envelope, where TMEM147 localizes (Thomas et al., 2022).
