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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 23, 2024 | The c.1043C>T (p.A348V) alteration is located in exon 6 (coding exon 6) of the NPTN gene. This alteration results from a C to T substitution at nucleotide position 1043, causing the alanine (A) at amino acid position 348 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
