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.605G>T (p.G202V) alteration is located in exon 4 (coding exon 4) of the NPAS4 gene. This alteration results from a G to T substitution at nucleotide position 605, causing the glycine (G) at amino acid position 202 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
