Genes affected
NPBWR2 (HGNC:4530): (neuropeptides B and W receptor 2) The protein encoded by this gene is an integral membrane protein and G protein-coupled receptor. The encoded protein is similar in sequence to another G protein-coupled receptor (GPR7), and it is structurally similar to opioid and somatostatin receptors. This protein binds neuropeptides B and W. This gene is intronless and is expressed primarily in the frontal cortex of the brain. [provided by RefSeq, Jul 2008]
MYT1 (HGNC:7622): (myelin transcription factor 1) The protein encoded by this gene is a member of a family of neural specific, zinc finger-containing DNA-binding proteins. The protein binds to the promoter regions of proteolipid proteins of the central nervous system and plays a role in the developing nervous system. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 10, 2021 | The c.610C>T (p.P204S) alteration is located in exon 1 (coding exon 1) of the NPBWR2 gene. This alteration results from a C to T substitution at nucleotide position 610, causing the proline (P) at amino acid position 204 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
