The variant received -3 classification points (ACMG Germline Pathogenicity v2019). PM2_SupportingBS2

The NM_207172.2(NPSR1):c.290C>T (p.Thr97Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.00000627 (AC=10) in the gnomAD database across 1,595,424 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000655. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

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 ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Likely_benign. The variant received -3 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PM2Absent/extremely low in population databases		Rare in gnomAD for AD/XL gene (popmax AF below threshold) — PM2 Supporting; GnomAD popmax AF = 0.0000655 — borderline rare for AD/XL gene (threshold 0.0001) — PM2 supporting.
	BS2Observed in healthy adult		Pure AD gene with cumulative gnomAD AC ≥5 — observed in healthy adults (BS2); GnomAD homozygous count = 0.; Cumulative gnomAD AC = 10 (pure AD gene, not AR).
