Genes affected
NPTN (HGNC:17867): (neuroplastin) This gene encodes a type I transmembrane protein belonging to the Ig superfamily. The protein is believed to be involved in cell-cell interactions or cell-substrate interactions. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.937G>A (p.E313K) alteration is located in exon 6 (coding exon 6) of the NPTN gene. This alteration results from a G to A substitution at nucleotide position 937, causing the glutamic acid (E) at amino acid position 313 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
