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 submitter | clinical testing | Ambry Genetics | Apr 27, 2022 | The c.655G>A (p.V219I) alteration is located in exon 4 (coding exon 4) of the NPTN gene. This alteration results from a G to A substitution at nucleotide position 655, causing the valine (V) at amino acid position 219 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
