Genes affected
NPAS2 (HGNC:7895): (neuronal PAS domain protein 2) The protein encoded by this gene is a member of the basic helix-loop-helix (bHLH)-PAS family of transcription factors. A similar mouse protein may play a regulatory role in the acquisition of specific types of memory. It also may function as a part of a molecular clock operative in the mammalian forebrain.

NPAS2-AS1 (HGNC:40408): (NPAS2 antisense RNA 1)
