Genes affected

NPAS3 (HGNC:19311): (neuronal PAS domain protein 3) This gene encodes a member of the basic helix-loop-helix and PAS domain-containing family of transcription factors. The encoded protein is localized to the nucleus and may regulate genes involved in neurogenesis. Chromosomal abnormalities that affect the coding potential of this gene are associated with schizophrenia and cognitive disability. Alternate splicing results in multiple transcript variants.

Jan 23, 2023

The c.646C>A (p.P216T) alteration is located in exon 6 (coding exon 6) of the NPAS3 gene. This alteration results from a C to A substitution at nucleotide position 646, causing the proline (P) at amino acid position 216 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
