Genes affected

NETO2 (HGNC:14644): (neuropilin and tolloid like 2) This gene encodes a predicted transmembrane protein containing two extracellular CUB domains followed by a low-density lipoprotein class A (LDLa) domain. A similar gene in rats encodes a protein that modulates glutamate signaling in the brain by regulating kainate receptor function. Expression of this gene may be a biomarker for proliferating infantile hemangiomas. A pseudogene of this gene is located on the long arm of chromosome 8. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2281521).

Ambry Genetics

Oct 28, 2023

The c.1135G>A (p.A379T) alteration is located in exon 9 (coding exon 9) of the NETO2 gene. This alteration results from a G to A substitution at nucleotide position 1135, causing the alanine (A) at amino acid position 379 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
