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.

The c.215A>G (p.Q72R) alteration is located in exon 4 (coding exon 3) of the NPAS2 gene. This alteration results from a A to G substitution at nucleotide position 215, causing the glutamine (Q) at amino acid position 72 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
