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)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 30, 2024The c.1165C>T (p.R389W) alteration is located in exon 13 (coding exon 12) of the NPAS2 gene. This alteration results from a C to T substitution at nucleotide position 1165, causing the arginine (R) at amino acid position 389 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
