Genes affected

NPAS4 (HGNC:18983): (neuronal PAS domain protein 4) NXF is a member of the basic helix-loop-helix-PER (MIM 602260)-ARNT (MIM 126110)-SIM (see SIM2; MIM 600892) (bHLH-PAS) class of transcriptional regulators, which are involved in a wide range of physiologic and developmental events (Ooe et al., 2004 [PubMed 14701734]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.961A>G (p.S321G) alteration is located in exon 7 (coding exon 7) of the NPAS4 gene. This alteration results from a A to G substitution at nucleotide position 961, causing the serine (S) at amino acid position 321 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
