Genes affected
NETO1 (HGNC:13823): (neuropilin and tolloid like 1) This gene encodes a transmembrane protein containing two extracellular CUB domains followed by a low-density lipoprotein class A (LDLa) domain. This protein is thought to play a critical role in spatial learning and memory by regulating the function of synaptic N-methyl-D-aspartic acid receptor complexes in the hippocampus. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 13, 2023The c.803G>A (p.R268H) alteration is located in exon 7 (coding exon 7) of the NETO1 gene. This alteration results from a G to A substitution at nucleotide position 803, causing the arginine (R) at amino acid position 268 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
