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]

NPBWR2 links:

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]

Sep 14, 2023

The c.703C>T (p.L235F) 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 703, causing the leucine (L) at amino acid position 235 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
