De novo variants of NR4A2 are associated with neurodevelopmental disorder and epilepsy.

ABSTRACT:

Purpose

This study characterizes the clinical and genetic features of nine unrelated patients with de novo variants in the NR4A2 gene.

Methods

Variants were identified and de novo origins were confirmed through trio exome sequencing in all but one patient. Targeted RNA sequencing was performed for one variant to confirm its splicing effect. Independent discoveries were shared through GeneMatcher.

Results

Missense and loss-of-function variants in NR4A2 were identified in patients from eight unrelated families. One patient carried a larger deletion including adjacent genes. The cases presented with developmental delay, hypotonia (six cases), and epilepsy (six cases). De novo status was confirmed for eight patients. One variant was demonstrated to affect splicing and res
