Genes affected
NPAS1 (HGNC:7894): (neuronal PAS domain protein 1) The protein encoded by this gene is a member of the basic helix-loop-helix (bHLH)-PAS family of transcription factors. Studies of a related mouse gene suggest that it functions in neurons. The exact function of this gene is unclear, but it may play protective or modulatory roles during late embryogenesis and postnatal development. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2022The c.109C>G (p.P37A) alteration is located in exon 1 (coding exon 1) of the NPAS1 gene. This alteration results from a C to G substitution at nucleotide position 109, causing the proline (P) at amino acid position 37 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
