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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.632C>T (p.T211I) alteration is located in exon 8 (coding exon 7) of the NPAS2 gene. This alteration results from a C to T substitution at nucleotide position 632, causing the threonine (T) at amino acid position 211 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
