Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_002522.4(NPTX1):​c.1286G>C​(p.Arg429Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R429H) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: NPTX1 NM_002522.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.59

Genes affected

NPTX1 (HGNC:7952): (neuronal pentraxin 1) NPTX1 is a member of the neuronal pentraxin gene family. Neuronal pentraxin 1 is similar to the rat NP1 gene which encodes a binding protein for the snake venom toxin taipoxin. Human NPTX1 mRNA is exclusively localized to the nervous system.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
