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]

The c.616G>A (p.G206S) alteration is located in exon 5 (coding exon 5) of the NPAS1 gene. This alteration results from a G to A substitution at nucleotide position 616, causing the glycine (G) at amino acid position 206 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
