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.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0011625588).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.191 is higher than 0.05.
