The variant received 2 classification points (ACGS-UK Somatic Oncogenicity v2025). O3_Moderate

The NR_015356.2(NPSR1-AS1):n.172-10086C>A variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: NR_015356.2 is not a MANE Select or MANE Plus Clinical transcript for NPSR1-AS1; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]

  Inheritance: AD Classification: LIMITED Submitted by: PanelApp Australia

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]

Classification according to ACGS-UK Somatic Oncogenicity v2025
