Genes affected

NPSR1 (HGNC:23631): (neuropeptide S receptor 1) This gene encodes a member of the vasopressin/oxytocin subfamily of G protein-coupled receptors. The encoded membrane protein acts as a receptor for neuropeptide S and affects a variety of cellular processes through its signaling. Increased expression of this gene in ciliated cells of the respiratory epithelium and in bronchial smooth muscle cells is associated with asthma. Polymorphisms in this gene have also been associated with asthma susceptibility, panic disorders, inflammatory bowel disease, and rheumatoid arthritis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

NPSR1-AS1 (HGNC:22128): (NPSR1 antisense RNA 1) This gene is located within a region that has been associated with asthma susceptibility. The locus is considered non-protein-coding based on lack of protein homology and a lack of experimental support for an encoded protein. Three alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, May 2010]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.52 is higher than 0.05.
